expat install libapreq2-2.0.5-dev

[Marc Lambrichs]

I'm trying to install libapreq2-2.0.5-dev on freebsd 5.4 box. Error 
"/usr/bin/ld: cannot find -lexpat" pops up. I've checked 
/usr/local/lib/libexpat.a exists and in the Makefile
libdir is ok ( /usr/local/lib ) and
APR_LDFLAGS contains -L/usr/local/lib
What's wrong?
Cheers,
Marc
