But perhaps grabbing different portions of the libraries.  Is your
environment set up the same way on both machines (BSD vs. POSIX vs.
XOPEN vs. SYSTEM_V, etc.)?

Also, considering the number of symbolic links in the pathnames for the
compiler and libraries, it is worth checking again to see if both machines
are really getting the same ones.

(Sorry, I'm not allowed to do any kernel work or other things that might
help answer your problem, but the matter of identical binaries raises
slightly different questions.)
