Hi,
I'm sorry I can't help on such problems. It is very far from my
understanding. Can't we just use the testsuite apart from package
building to be sure that our packaging is OK and then distribute a
version without the .idl files ? Testing should be our duty and not for
the buildd machines ?
My two cents... xavier
PS:any comment on my last changes (minors) ?
