Compiling under Solaris 8

Hi,
I'm installing PostgreSQL 7.2.0 on a Sun Netra X1, Solaris 8.

The compile finishes normally, and postmaster and the like all run fine.

My problem is that I want to use the command history, which is enabled by
having the readline libraries installed.

If I download and install readline 4.2 from www.sunfreeware.com , then do a
./configure, i get...

<snip>
checking for readline... no
...
checking for readline/readline.h... yes
checking for readline/history.h... yes
</snip>
and the resultant psql doesn't have command history.

If I download the source for readline 4.2 and compile and install (make
install) i get the following.

<snip>
checking for readline... yes (-lreadline -ltermcap)
...
checking for readline/readline.h... yes
checking for readline/history.h... yes
...
checking for sigsetjmp... yes
checking for optreset... no
checking test program... failed
configure: error:
*** Could not execute a simple test program. This may be a problem
*** related to locating shared libraries. Check the file 'config.log'
*** for the exact reason.
</snip>

config.log:

int main() { return 0; }

</snip>

I'm fairly new to linux and solaris, but I'm guessing that ld isn't happy
with the compiled readline libs.

Is there something I'm not doing that I should be? please help...
