Hello, I downloaded Tk-804.027.tar.gz and tried to install the Tk module with tar -zxvpf Tk-804.027.tar.gz cd Tk-804.027.tar.gz perl Makefile.PL make (make test) However, make did not work, reporting: make: *** No rule to make target `/System/Library/Perl/5.8.6/darwin-thread-multi-2level/CORE/config.h', needed by `Makefile'. Stop. I am very new to both perl and the Mac. Is there anybody who knows, how I could overcome this problem ? Thank you very much Michael
