Fail to make 6.4.2

Hello,

I am trying to compile Postgress v6.4.2 on Redhat v5.1 Linux v2.1.125
on a Pentium II system. My configure command was:
 ./configure --with-template=linux_i386
and the make failed.   The last few lines of the log are:

gmake[3]: Leaving directory `/usr/src/pgsql/src/backend/optimizer/geqo'
for i in path plan prep util geqo; do gmake -C $i path/SUBSYS.o; done
gmake[3]: Entering directory `/usr/src/pgsql/src/backend/optimizer/path'

Any suggestions will be welcome.
