This has nothing to do with symlinks.  You have the same problem if you 
try to run /bin/pdftex directly.  Furthermore, the files in /bin are the 
same as those in /usr/bin (see /etc/fstab), so you can't remove files or 
symlinks in /bin without also removing them from /usr/bin.

The problem here is that the tex-related binaries don't find the 
configuration file /usr/share/texmf/web2c/texmf.cnf when invoked as 
/bin/* rather than /usr/bin/*.  I'll fix this and release an updated 
texlive package shortly.
