[Zope-DB] problem with make when installing ZPyGreSQLDA

[Zerrin Çakmakkaya]

Hi,

I'm trying to install ZPyGreSQLDA.. I extracted ZPyGreSQLDA...tgz, when
I'm in /usr/local/zope. ZPyGreSQLDA directory is created in
/usr/local/zope/lib/python/Products. I changed the directory to /src and
wrote:

make -f Makefile.pre.in boot

when I write

make

I receive following error:

gcc -shared  ./pgmodule.o  -lpq -lcrypt  -o ./_pgmodule.so
/usr/bin/ld: cannot find -lpq
collect2: ld returned 1 exit status
make: *** [_pgmodule.so] Error 1

Why?
