it seems to me that: ftp://ftp.rpm.org/pub/rpm/dist/rpm-4.0.x/ is more authoratative then: ftp://ftp.redhat.com/pub/code/popt (which is listed in the popt.h file) Even if it was ftp.redhat.com the code directory was moved to /pub/redhat/code/popt but that directory has a only version 1.2 Also, the spec in rh7 says License: GPL, and the tar ball says: License: LGPL, when the COPYING file says XFree86 License. Please update the popt.h header, and .spec file to be accurate. Thanks
popt has a X Consortium license (per Erik Troan). This should be reflected in popt sources from CVS.
