configure problem

[Wendy Palm]

i'm having a problem configuring cvs on a particular cray architecture.
cvs-1.11 configured and installed just fine,
but cvs-1.11.3 and cvs-1.11.5 fails at the

checking how to run the C preprocessor... /lib/cpp
configure: error: C preprocessor "/lib/cpp" fails sanity check

i've looked at that section of the code, and i can't figure out what
the heck it's trying to do.

on this machine, cpp is in /opt/PE/bin/cpp, which is in my path.

here is the config.log
This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by Concurrent Versions System (CVS) configure 1.11.3, which was
generated by GNU Autoconf 2.53.  Invocation command line was

  $ ./configure --prefix=/opt/open/33
