postgis error in compiling on mac os x snow leopard

I'm trying to compile postgis 1.5.2 on Mac OS X and running Postgresql 8.4 (installed via one click installer from enterprisedb).

I've used kyngchaos's GDAL complete binary package for postgis and added this to my .bash_profile:

export PATH=/Library/Frameworks/UnixImageIO.framework/Programs:$PATH
export PATH=/Library/Frameworks/PROJ.framework/Programs:$PATH
export PATH=/Library/Frameworks/GEOS.framework/Programs:$PATH
export PATH=/Library/Frameworks/SQLite3.framework/Programs:$PATH
export PATH=/Library/Frameworks/GDAL.framework/Programs:$PATH

I've downloaded the current postgis source and ran ./configure it stops at the end with:

checking PostgreSQL version... PostgreSQL 8.4.3
checking libpq-fe.h usability... yes
checking libpq-fe.h presence... yes
checking for libpq-fe.h... yes
checking开发者_开发技巧 for PQserverVersion in -lpq... no
configure: error: could not find libpq

Thus not making the postgis_config.h file for make.

Check the configure.log. It can be some error related with libpq or some library that libpq needs.
