Compilation Problem

I'm trying to install DBD-Pg-1.22 on CygWin. I have postgresql and DBI up
and running but i can't get DBD-Pg-1.22 working.
I receive the following error executing make:

$ make
rm -f blib/arch/auto/DBD/Pg/Pg.dll
LD_RUN_PATH="" ld2 -s -L/usr/local/lib Pg.o dbdimp.o -o

What can the problem be???
