Postgres 8.0.1 configure failed

I am installing postgres 8.0.1 (solaris 9 SPARC), but while configure it is
failing. (I have already installed gcc/tcl/tk and tested a simple c program)

./configure --enable-integer-datetimes --prefix=/usr/local/pgsql
--with-tclconfig=/usr/local/lib --with-tcl

--------------------------------------------

ERROR

configure: error:
