Linux was much less widely used and less on the radar then, compared to nowadays. That may be why there was no Linux port of BP7. Also, Borland did a Linux port of Delphi - called Kylix - later, but it never got popular and was later stopped. IIRC, it was free or had a free trial, and I had tried it a little. I read on the net that Linux people preferred C/gcc and its toolchain ( me too :), that may be why Kylix didn't get popular.
