Forum OpenACS Q&A: Response to Make command fails for AOLserver PGSQL Driver

Like Philip, I found libpg-fe.h in /usr/include/pgsql, and I set
POSTGRES = /usr/include/pgsql
in the nspostgres/Makefile However, there is another definition in the same Makefile:
MODLIBS = $(POSTGRES)/libs/libpq.a
for which there is no corresponding module name. There does exist a $(POSTGRES)/libs directory, but there are only two .h files, and no .a files I went ahead and compiled postgres without the MODLIBS definition, but does anyone know where the libpq.a file is, and whether it is kosher to compile without it? Thanks,
