I'm fighting against this weirdness since some days: if I build mpl
debian package on my system, it builds normally, but if I build the
package in a clean chroot it fails, and I only noticed because I want
to create a link in doc/build/html/_static dir, that's missing. and
I'm wondering why! I can't seem to find a clear answer to that, so I'm
asking for any advice yo might have.
The full log of the package build in the chroot is at  (it's quite
large expanded); at the end of the file there are some ls -lR to try
to identify what's going wrong.
Thanks in advance,
