New description:
A problem with cddlib-094f.p2.spkg is that it patches upstream source
using a patch file, rather than copying a patched file over to the
appropriate place under the src/ directory. Consequently, there is no
clean separation between upstream source and patches that we apply to
cddlib-094f. Looking at spkg-install of cddlib-094f.p2.spkg, you get these
two lines for applying Sage-specific patches:
{{{
cp patches/allfaces.c src/src/
patch -p0 < patches/cdd_both_reps-make.patch
}}}
The first line is the preferred way to patch an upstream source because it
copies the patched file patches/allfaces.c over to src/src/. This issue is
reported on [http://groups.google.com/group/sage-
devel/browse_thread/thread/e599fd37de909264 sage-devel].
