Parser problems when installing PGSQL V6.4 on Redhat 5.1

I am trying to install Postgres V6.4 on my Redhat box, but cannot find a way
past the following error which I get after "make all >& make.log &":-

make -C parser all

I have bison in /usr/bin and a line in Makefile.global sets "YACC =
/usr/bin/bison".  I configure with the line
"./configure -with-template=linux_i386 -with-perl"

Any suggestions would be greatly appreciated.
