it occurs only for pdftosrc, and it is fixed by removing libpdftex.a
from the link command:

this fails:

/bin/bash ./libtool --tag=CXX   --mode=link xlC  -O2 -qmaxmem=262144 -qarch=com -qlanglvl=extended   -o pdftosrc pdftosrc-pdftosrc.o libpdftex.a /usr/local/vvv/src/source/Work/libs/libpng/libpng.a /usr/local/vvv/src/source/Work/libs/zlib/libz.a /usr/local/vvv/src/source/Work/libs/xpdf/libxpdf.a /usr/local/vvv/src/source/Work/libs/obsdcompat/libopenbsd-compat.a libmd5.a lib/lib.a /usr/local/vvv/src/source/Work/texk/kpathsea/libkpathsea.la -lm 
libtool: link: xlC -O2 -qmaxmem=262144 -qarch=com -qlanglvl=extended -o pdftosrc pdftosrc-pdftosrc.o  libpdftex.a /usr/local/vvv/src/source/Work/libs/libpng/libpng.a /usr/local/vvv/src/source/Work/libs/zlib/libz.a /usr/local/vvv/src/source/Work/libs/xpdf/libxpdf.a /usr/local/vvv/src/source/Work/libs/obsdcompat/libopenbsd-compat.a libmd5.a lib/lib.a /usr/local/vvv/src/source/Work/texk/kpathsea/.libs/libkpathsea.a -lm

this works:

/bin/bash ./libtool --tag=CXX   --mode=link xlC  -O2 -qmaxmem=262144 -qarch=com -qlanglvl=extended   -o pdftosrc pdftosrc-pdftosrc.o /usr/local/vvv/src/source/Work/libs/libpng/libpng.a /usr/local/vvv/src/source/Work/libs/zlib/libz.a /usr/local/vvv/src/source/Work/libs/xpdf/libxpdf.a /usr/local/vvv/src/source/Work/libs/obsdcompat/libopenbsd-compat.a libmd5.a lib/lib.a /usr/local/vvv/src/source/Work/texk/kpathsea/libkpathsea.la -lm 
libtool: link: xlC -O2 -qmaxmem=262144 -qarch=com -qlanglvl=extended -o pdftosrc pdftosrc-pdftosrc.o  /usr/local/vvv/src/source/Work/libs/libpng/libpng.a /usr/local/vvv/src/source/Work/libs/zlib/libz.a /usr/local/vvv/src/source/Work/libs/xpdf/libxpdf.a /usr/local/vvv/src/source/Work/libs/obsdcompat/libopenbsd-compat.a libmd5.a lib/lib.a /usr/local/vvv/src/source/Work/texk/kpathsea/.libs/libkpathsea.a -lm

and this was the link command in TL2008:

/bin/sh ../libtool --mode=link xlC -o pdftosrc  pdftexdir/pdftosrc.o ../../libs/xpdf/xpdf/libxpdf.a ../../libs/xpdf/goo/libGoo.a ../../libs/xpdf/fofi/libfofi.a -lm 
xlC -o pdftosrc pdftexdir/pdftosrc.o  ../../libs/xpdf/xpdf/libxpdf.a ../../libs/xpdf/goo/libGoo.a ../../libs/xpdf/fofi/libfofi.a -lm

thus, is it possible to remove libpdftex.a from the link command? (and why
was it added there?)

Best,
