Done that several times -- no dice
I normally do not use TL, but looked into it, and the texmfcnf.lua script
distributed with texlive does not look right. I am attaching the output of
mtxrun --generate that I get. Note the following liines:
resolvers       | resolving | variable 'SELFAUTOLOC' set to '/usr/bin'
resolvers       | resolving | variable 'SELFAUTODIR' set to '/usr'
resolvers       | resolving | variable 'SELFAUTOPARENT' set to '.'
It looks as if you were using Debian/Ubuntu? Or any other flavour of
Linux with a native TeX Live package?

Now, the /usr/share/texmf/web2c/texmfcnf.lua file says:
TEXMFSYSVAR     = "selfautoparent:texmf-var",
 TEXMFVAR        = "home:.texlive2012/texmf-var",
....
 TEXMFMAIN       = "selfautoparent:texmf",
 TEXMFDIST       = "selfautoparent:texmf-dist",
....
Note from the mtxrun that selfautoparent is set to '', therefore, TEXMFMAIN
is set to 'texmf' and TEXMFDIST is set to 'texmf-dist'. And therefore,
`mtxrun --generate` is not scanning the right trees, therefore does not
build a cache of the right trees, and consequently, cannot find
mtx-context.lua.
To check my theory, I followed the following steps:
1. Create a directory ~/mytexmfcnf and copied the texmfcnf.lua file from
/usr/share/texmf/web2c/ to this directory.
2. Open ~/mytexmfcnf/texmfcnf.lua and change
%s/selfautoparent:/\/usr\/share\/
3. Run
TEXMFCNF=~/mytexmfcnf mtxrun --generate
4. Run
TEXMFCNF=~/mytexmfcnf context --version
which then gives
mtx-context     | ConTeXt Process Management 0.52
mtx-context     |
mtx-context     | main context file:
/usr/share/texmf-dist/tex/context/base/context.mkiv
mtx-context     | current version: 2012.05.30 11:26
So I wonder how does context (MkIV) work at all with TL2012!
Maybe it just doesn't work with your linux box :P
One explanation could be that texmfcnf.lua hasn't been configured properly.
It works with plain TeX Live with default installation.

MacPorts would do the following:

post-patch {
    foreach x {texmf.cnf.d/10paths.cnf texmfcnf.lua texlive-update-cnf} {
        reinplace "s|@@PREFIX@@|${prefix}|g" ${worksrcpath}/${x}
        reinplace "s|@@TEXMFMAIN@@|${texlive_texmfmain}|g" ${worksrcpath}/${x}
        reinplace "s|@@TEXMFDIST@@|${texlive_texmfdist}|g" ${worksrcpath}/${x}
        reinplace "s|@@TEXMFPORTS@@|${texlive_texmfports}|g" ${worksrcpath}/${x}
        reinplace "s|@@TEXMFLOCAL@@|${texlive_texmflocal}|g" ${worksrcpath}/${x}
        reinplace "s|@@TEXMFSYSVAR@@|${texlive_texmfsysvar}|g"
${worksrcpath}/${x}
        reinplace "s|@@TEXMFSYSCONFIG@@|${texlive_texmfsysconfig}|g"
${worksrcpath}/${x}
        reinplace "s|@@TEXMFHOME@@|${texlive_texmfhome}|g" ${worksrcpath}/${x}
        reinplace "s|@@TEXLIVE_BINDIR@@|${texlive_bindir}|g" ${worksrcpath}/${x}
    }
}

To Bill: can you try
    which luatex context
    sudo which luatex context
and in particular because you have TeX Live installed in home dir, I
would suggest not to run any command as sudo at all. In particular,
don't try to run "mtxrun --generate" or "context --make" as sudo. It
might be that the cache is not writable by you any more. But then
again - something seems to be wrong with your configuration. How
exactly did you install TeX Live.  Where do you have any texmfcnf.lua?
Please also post the output of a working ConTeXt run and/or "mtxrun
--generate", in particular the part that Aditya posted (definition of
SELFAUTOLOC etc.).
