After upgrading from Squeeze to Wheezy, I'm unable to use my mod_perl

Application works fine after removing the reference to
Apache2::SizeLimit in Apache's configuration file and restarting.
Working without Apache2::SizeLimit makes it very hard to control the
resource consumption of the mod_perl application, so it's not an
acceptable workaround.
After installing Linux::Pid everything works.
Looking at /usr/lib/perl5/Apache/SizeLimit/Core.pm, there's a BEGIN
block (line 134) having
elsif ($Config{'osname'} eq 'linux') {
_load('Linux::Pid');
so it does use Linux::Pid. It also *tries* to use Linux::Smaps a couple
of lines after, but this time it's optional and doesn't fail if it isn't
there.
Neither Linux::Pid nor Linux::Smaps is available on Debian Wheezy nor
Sid, at the time of this writing. I believe Linux::Pid should've been a
part of Debian Wheezy for Apache2::SizeLimit to work properly.
