Problem with "compress" - can not compile libXpm, compress not found, set XPM_PATH_COMPRESS or use --disable-stat-zfile

checking for compress... no

configure: error: compress not found, set XPM_PATH_COMPRESS or use --disable-stat-zfile

^^^

Would it be possible to show a bit more information? Perhaps in the README or so.

Right now I do not know what "compress" is. It is a binary I assume? To which other program does it belong?

I'll use the --disable-stat-zfile flag for now, but perhaps compress is important so I'd prefer libXpm to have that when I try to compile it. Thank you for reading.
