compiling psqlodbc for unixodbc -- problems

Can anybody provide me with some help on this issue?

I'm attempting to build psqlodbc-07.03.0200 in an attempt to use this
driver with unixodbc.

I first configure:
# ./configure --with-unixodbc
I don't see any errors when I do this.

Then I "make":
#make

And this is what I get:

make all-am
source='info.c' object='info.lo' libtool=yes depfile='.deps/info.Plo'
tmpdepfile='.deps/info.TPlo' depmode=gcc /usr/local/bin/bash ./depcomp
/usr/local/bin/bash ./libtool --mode=compile gcc -DHAVE_CONFIG_H -I. -I.

I am running FreeBSD-4.9-RELEASE-p3
Postgresql-7.3.5_1 (installed from ports)
unixODBC-2.2.8 (installed from ports)

Thanks for any input you can provide.
