Compile Info

I on a SUnOS 5.6 box without root access trying to compile Postgres 6.3.2
and getting the following:

--------------------------------------------------------------------
You must use GNU make to use Postgres. It may be installed
on your system with the name 'gmake'.

NOTE: If you are sure that you are using GNU make and you are
still getting this message, you may simply need to run
the configure program.
--------------------------------------------------------------------

My make command line: make all > & make.log &

The configure looked like: ./configure --prefix=/my_path/pgsql --with-template=sparc_solaris-gcc

What am I doing wrong?

Thanks
