I migrated my texlive2007 tree to a new disk and now I encounter  
permission difficulties on context format generation. Calling the  
bashrc alias:

alias formats='texmfstart texexec --make en; texmfstart texexec --make  
--alone metafun

After the normal (error) messages about ls-R updating I get a  
permission error:

TeXExec | using search method 'kpsewhich'
TeXExec | updating file database
mktexlsr: Updating /Users/hans/Tex/texmf-private/ls-R...
mktexlsr: /usr/local/texlive/2007/texmf: directory not writable.  
Skipping...
<these are expected, no access for me to these directories>
mktexlsr: Done.
TeXExec | using tex engine pdftex
TeXExec | using tex format path ./pdftex
TeXExec | unable to make format due to lack of permissions

and on calling the following alias:

alias texversion='texmfstart texexec.pl --version; rm mpgraph.mp  
texvers-mpgraph.mp'

I get:

fmtutil: format directory `/web2c' does not exist.
kpathsea: Running mktexfmt context.fmt
fmtutil: format directory `/web2c' does not exist.

In my .bashrc I have:
# TeX variables
CONTEXT_RUBY=/usr/local/texlive/texmf-local/scripts/context/ruby
TEX_HOME=/usr/local/texlive/2007
TEXMFCACHE=/Users/hans/Temp
OSFONTDIR=/Library/Fonts
TEXMFCNF=/usr/local/texlive/texmf-local/web2c
TEXMF="{/Users/hans/Tex/texmf-private,/usr/local/texlive/texmf- 
context,/usr/local/texlive/texmf-local,/usr/local/texlive/2007/texmf,/ 
usr/local/texlive/2007/texmf,/usr/local/texlive/2007/texmf-config,/usr/ 
local/texlive/2007/texmf-dist,/usr/local/texlive/2007/texmf-doc,/usr/ 
local/texlive/2007/texmf-var}"
TEXFORMATS=/usr/local/texlive/2007/texmf-config/web2c

nor did work:
TEXFORMATS=/Users/hans/.texlive2007/texmf-var/web2c/pdftex

The idea is to have the formats locally under .texlive2007 in my home  
directory.

Can someone enlighten me where the base of respectively ./pdftex and / 
web2c is supposed to be? I thought I did set my environment variables  
just as I did previously, when it worked. Why suddenly these  
apparently incomplete paths? I MUST have some pathvariable WRONG, but  
which one is it?
