I agree that $Config{perlpath} is wrong, but no great right solution
seems to present itself. What's a script to do if it wants to invoke
the same perl executable that's currently running? In some cases
neither $^X or $Config{perlpath} will do the trick. $^X won't work
because it might just be something like 'perl' and not resolve correctly
in the PATH, and $Config{perlpath} won't work because it doesn't change
values to reflect the true location of the perl executable if it moves
after (or before!) installation.
Anyway, I'd love to know some way of handling this. It'd be useful for
Module::Build. Currently I'm just using $Config{perlpath}.
