Thanks for your continued testing and feedback.  I've committed
Patrice's fix and further fixes including one of those two patches
(as df28d148ab26612).  (I realised too late that I missed the commit
summary line but it should be clear from the rest of the commit message
what the commit is for.)

In the other commit I made (a78e787fe3a) it was a simpler fix than the
one you sent - hopefully it doesn't make a difference.  (I want to keep
it as simple and comprehensible as possible so there is not so much
for someone to make sense of in the future when fixing any other problems -
personally, my understanding of these issues and willingness to fix them
is going down over time.)

This failure is for building pod2texi.texi.  It requires running the
pod2texi program, but this is not ready to run yet.  It is probably easy
enough to make work by adding more Makefile rules but I wonder how many
similar problems could exist.

One idea is to run pod2texi instead of pod2texi.pl, setting
TEXINFO_DEV_SOURCE.  There would be a rule for regenerating pod2texi
by running "make" in "Pod-Simple-Texinfo".  ModulePath.pm would be
a dependency of pod2texi.  This would avoid having to add rules to
regenerate ModulePath.pm in multiple places, which is less obvious than
a rule to generate pod2texi.  I can probably try to implement this in the
next day or two.
