in reply to Re^2: Find installed Perl modules matching a regular expression
in thread Find installed Perl modules matching a regular expression

Nice idea. However, it does not seem to work if a sub-directory of a directory in @INC has been modified. Since directories under @INC can be arbitrarily deep, it would be necessary to perform a find on all directories, which is what the init file was designed to avoid.

Perhaps there is a more efficient way to check if any directory has been modified throughout a tree.

    I don't think that is neccessary. perllocal.pod lives in @INC, and when you install modules (with ExtUtils::MakeMaker), perllocal.pod gets updated, and the directory mtime gets updated.

    Since Module::Build doesn't update perllocal (yet), and neither do ppm or apt-get..., after installing a module an admin might touch @INC 

    $atime = $mtime = time;
utime $atime, $mtime, @INC;

    Additional directories to check might be 

    perl -V:installbin -V:installscript -V:installsitebin
