Problem with installing postgreSQL

Hi there.

I'm trying to install postgreSQL 6.3.2 on a Sun Sparc Station 5 with Solaris 2.6.

but when running make I get the following:

gcc -I../../../include -I../../../backend -Wall -Wmissing-prototypes -I../include -DMAJOR_VERSION=1 -DMINOR_VERSION=1 -DPATCHLEVEL=0 -DINCLUDE_PATH=\"/usr/local/pgsql/include\" -c y.tab.c
/usr/ccs/bin/yaccpar: In function `yyparse':

make[1]: *** [all] Error 2

I'm not a C programmer ... can anyone help me?
