The real problem (or feature) is that large parts of the 
texmf.cnf file relies on the magic variable $SELFAUTODIR
which is set from argv[0] of the calling program. Very 
convenient as long as you place all programs in their standard
location, but a problem otherwise.

If you want to debug the Kpathsea file searching, I suggest
using the $KPATHSEA_DEBUG variable instead, see 'info kpathsea'.
