I just did 'make distclean' 'make install' all went well, sorta
kinda. The only problems I saw was Semantic related (but we know
about that).

That

Yes it should, and to be honest, I'm surprised that it didn't for you.

OK confession time... Before the advent of pdepends.mk, the packages
built fine for me, after pdepends.mk, they still built fine for me.
Because of that I never looked closely at what they were supposed to
do. I had noticed that they don't get built when building a package
from within a package directory
(./packages/xemacs-packages/pkgname/).
Sorry Jan. I really did mean to bring this up with you, but because
it didn't appear broken, I never thought about it.

What should happen, and did for me today...
make distclean -- cleans out any generated file
make (anything except the clean targets or html) -- should first of all do a
'make autoloads', then do whatever else.
Once all the autoloads are built, you should be able to build any
package in the tree.
I'll do a bit of investigating and see what I come up with.
