Trying to run ./configure fails with the message:

configure: error: cannot run C++ compiled programs.

The config.log file reports:

version 'GCC_3.3' not found (required by
usr/lib/libstdc++.so.6)

FC3 is delivered with gcc 3.4.2.

What is the best path to a fix for this?  Must I
regress to an older compiler?

This is clearly a bug in your gcc installation - perhaps
some library is not up-to-date, or libstdc++ was compiled
with the wrong compiler. You should report this to the FC3
developers.

As a work-around, you can configure your Python --without-cxx.

The fc3 group begs to differ with the assessment.  Perhaps
someone can comment on the response to Buzilla 146563.  If
this bug is closed again, that's fine.  I do not think I
would try to reopen it.

/usr/local/abinitio/lib/libgcc_s.so.1: version `GCC_3.3' not
found (required by
/usr/lib/libstdc++.so.6)

/usr/local/abinitio/lib/libgcc_s.so.1 is not part of Fedora
Core, and is
older than the system libgcc_s.so.1 in /lib/.
The bug is that you are thus overriding a system library
with an incompatible
(well, in this case likely just older) one.
You need to avoid that.
In this particular case I guess just rm -f
/usr/local/abinitio/lib/libgcc_s*
would DTRT (perhaps make a backup copy of that).

But it is certainly not a bug in the distro, but a problem
caused by badly
packaged 3rd party software.

My apologies.  The problem was another libgcc_s.so that was
installed by another third-party product, not Python.  Once
this was removed from LD_LIBRARY_PATH, it appears to be
successful.  Sorry.
