libpq errors when makeing postgres 7.0.2...

Dear All,

I have downloaded gcc and make from
www.sunfreeware.com in pkgadd format for solaris 7.
Then I have installed them
using pkgadd successfully. Now Iam trying to install
postgres 7.0.2. But i get the following errors when i
say make:-

****************************
make[2]: Entering directory
`/usr/share/src/postgresql-7.0.2/src/interfaces/libpq'
ar crs libpq.a `lorder fe-auth.o fe-connect.o
fe-exec.o fe-misc.o fe-print.o fe-
lobj.o pqexpbuffer.o dllist.o pqsignal.o inet_aton.o
| tsort`
/bin/sh: lorder: not found
/bin/sh: tsort: not found
/bin/sh: ar: not found
make[2]: *** [libpq.a] Error 1
make[2]: Leaving directory
`/usr/share/src/postgresql-7.0.2/src/interfaces/libpq
'
make[1]: *** [all] Error 2
make[1]: Leaving directory
`/usr/share/src/postgresql-7.0.2/src/interfaces'
make: *** [all] Error 2
*****************************

Please help me solve this prb. Is the prolem in the
installed gcc and make or with postgres source code
only.
Kindly mail me to my personal account
rajesh(at)intercept-india(dot)com & my postgres user group id
drajesh80(at)yahoo(dot)com(dot)
Thanks for all the suggestions.

Regards

Rajesh.
