$ objdump -p /sid/usr/bin/pdfetex | grep NEEDED
  NEEDED      libpng12.so.0
  NEEDED      libkpathsea.so.4
  NEEDED      libpoppler.so.0
  NEEDED      libcairo.so.2
  NEEDED      libXrender.so.1
  NEEDED      libX11.so.6
  NEEDED      libfontconfig.so.1
  NEEDED      libjpeg.so.62
  NEEDED      libfreetype.so.6
  NEEDED      libz.so.1
  NEEDED      libstdc++.so.6
  NEEDED      libm.so.6
  NEEDED      libgcc_s.so.1
  NEEDED      libc.so.6

At least libcairo is wrong;  I think that also libfontconfig, libjpeg,
libfreetype, and maybe libX11 and libXrender are wrong, because

- we don't configure with --with-system-foolib for these libraries

- there's no mention of the strings fontconfig and freetype at all in
  the sources related to pdfetex

- jpeg doesn't appear in any pdftex-related Makefile (snippet)

- without checking the sources, I'd be surprised if pdfetex used any X
  header files, since it's supposed to be a pure commandline program.  

Furthermore, none of these libraries is included in the upstream
tarball, but a static compile of pdftex with the standard upstream
configuration gives:

$ objdump -p /sid/usr/local/teTeX/bin/i686-pc-linux-gnu/pdfetex | grep NEEDED
  NEEDED      libstdc++.so.6
  NEEDED      libm.so.6
  NEEDED      libgcc_s.so.1
  NEEDED      libc.so.6

Regards, Frank
