Very Computer

Making a PostgresSql 6.4 installation I've got the message:
checking whether the C++ compiler (gcc  ) works... no
configure: error: installation or configuration problem: C++ compiler
cannot create executables.

In fact, doing the following test: gcc -o conftest conftest.C the
message is
gcc: installation problem, cannot exec `cc1plus': this file or directory
doesn't exist
(I'm often using gcc with standard c programs and it works perfectly)
:-)
I did "find / -name '*cc1plus*' -print" but cc1plus was not found.

I'm not familiar with C++ and I believed that it was a build as a
feature of gcc. So I re-installed gcc (2.7.2.3-11) and libg++
(2.7.2.8-9). Running again my test gave the same error.

I don't know what package is missing and where I can find cc1plus.

NB: I'm running Redhat 5.1 (Kernel 2.0.34) on a Pentium 100.

Thank you for any help
