SuSE Personal does not come packaged with a compiler.
You'll have to install GCC. You can find the SuSE RPM's to install them at ftp.suse.com/pub/suse/i386/9.1/suse/i586/
Which, incidentally, you can also find an RPM of pure-ftp so you could install it that way.
To make your life even easier, go into YAST -> Software -> Change Source of Installation -> Add
Then put 'ftp.suse.com' in the server name, and 'pub/suse/i386/9.1/suse/i586' in the directory entry. Now save it, go to Install / Remove Software, and all those packages at SuSE's FTP site will show up in YaST. You can install them directly from there.
