Configure script of bacula-2.4.1-r1 can't find Python.h if python2.6 used. Reproducible: Always Trivival patch of configure needed.
Created attachment 219255 [details, diff] app-backup/bacula/files/2.4.1/2.4.1-python2.6.patch Add epatch "${FILESDIR}"/${PV}/${PV}-python2.6.patch at the end of src_unpack function.
Will be fixed in 5.0.x ebuilds.
(In reply to comment #1) Thanks for the patch, this comes in handy as backup infrastructures are not things you want to arbitrarily upgrade ;)
