Error in compiling

Hi.

I'm trying to compile the postgreSQL on a Sun Sparc5 with Solaris 2.6 ... the first hint (installing bison) took me
further... but now another error occurs: 

make[3]: Leaving directory `/usr/share/src/pgsql/src/interfaces/ecpg/lib'
/usr/local/bin/make -C preproc all
make[3]: Entering directory `/usr/share/src/pgsql/src/interfaces/ecpg/preproc'

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

can someone help me any further?
