Do I need something special to make the @INC of a child process in a test the same as the parent?

I'm getting some odd test results for PerlPowerTools, my slow rollout
of an update to PPT (but spelled out for better discoverability). Some
of the programs require modules, which I've added to Makefile.PL, but
some testers seems to have the modules then can't find them.

http://www.cpantesters.org/distro/P/PerlPowerTools.html

In the t/compile.t, I call out to perl to do a syntax check, so I
figure in the subprocess it doesn't know the @INC of the parent
process.  (And, I've just read the wiki stuff about $^X, so I'll fix
that too).

Should I set PERL5LIB with the parent @INC or something similar?
