Readline library

I am compiling Postgres 6.5.1 on a Silicon Graphics machine running IRIX
6.5.4. For some reason, the configure command doesn't recognize where
the 'readline' libraries are. I have the libraries installed under
/usr/freeware/lib and /usr/freeware/include/readline. I have tried doing
an install using --with-include and --with-libs specifying these
directories, but it still doesn't seem to find them.

Where does the configure command look for the readline libraries? Is
there some other switch I can set in configure to look in these parts of
the directory?

Thanks.

Here's the listing of the two directories for readline:
--------------------------------------------------------
/usr/freeware/lib

exmh-2.0.2/        libdf.so.4.1       libpng.so*

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

rlstdc.h     tilde.h


Here's the command I try for configure:

o21:reina/ > ./configure --prefix=/usr/local/pgsql --without-CXX
--with-libraries=/usr/freeware/lib/
--with-includes=/usr/freeware/include/readline


Here's the response:


...
...
checking for main in -lreadline... no
checking for write_history in -lreadline... no
