I've compiled my own version of RPM and apt lorg3.2 with a few
additional paches to make sure I can fully relocate the macros and the
rpmrc files so that I'm completely directory indipendent and I can
install packages as a user in any given directory (that's part of my
Everything works well enough, but I get occasional deadlocks when
installing a package after having build it with rpmbuild. The actual
lock occurs in:

and if I strace the command I actually can see that it tries to open
