Patch to PP

[Ian Cass]

Hi,

The -l (--link) argument to pp generates an error if LD_LIBRARY_PATH does
not exist. Can I therefore suggest a patch to 'sub _find_shlib' something
similar to the following...

    if (not exists $ENV{$Config{ldlibpthname}}) {
        print "Can't find $file. Environment variable $Config{ldlibpthname}
does not exist.\n";
        return;
    }
