Hello Thomas, and thank you for the install guide.  Here are a few comments:

The cpml installer does not depend on bash (which provides /bin/sh on Debian), should it?  I don't see why...

Ah, so these are potato directions. :-)  The cpml/cxml installers should work on potato, but the ccc installer will depend on gcc-2.95 in woody/sid because of the libgcc.a location (otherwise it will break on upgrade of gcc), and none of them depend on rpm (they include a small perl rpm2cpio in postinst, like the realplayer installer package they're based on).

Question: I have it in the installer now, but why is -lots there?  Does ld provide inter-library dependencies, or is it just ignored?  I thought that's part of why libtool exists.

And it's not even clear cpml should depend on libots at all...

Okay, the cpml installer does all of this.

Does it just run create-comp-config.sh to do this, or is there more to the rpm's "postinst" script?  Anyone know how I can extract such scripts from a binary rpm?

Thanks again,
