Solaris 5.6 install problem

Hi !!
I am trying to install Postgresql-7.0.3 on the solaris 5.6 machine and
i am trying to configure it as a user and not as a root because i don't
have root access as it is my computer science departmental machine.
when i run a make it gives the following error:

gmake[3]: Leaving directory

Please if someone can help me out.
I was getting the same trouble with installing Apache WebServer in my
account and had to go and modify the "makefiles" to include
-lbind option in them. Do i have to do the same thing here as well, i
tried doing that though and it didn't work.

Regards,
Amit
