perl5.*: should use -Duseshrplib

[reg-macports.org@…]

perl5.8 and perl5.10 should be compiled with a shared perl library:

 http://search.cpan.org/perldoc?README.macosx#Known_problems says: The default of building Perl statically may cause problems with complex applications like Tk: in that case consider building shared Perl

Configure ... -Duseshrplib

but remember that there's a startup cost to pay in that case (see above "libperl and Prebinding").

However,  http://search.cpan.org/perldoc?README.macosx#libperl_and_Prebinding also says:

With 10.4 "Tiger" and newer, Apple has all but eliminated the performance penalty for non-prebound libraries.

---

As MacPorts requires OS X 10.5, performance is no longer a reason not to use -Duseshrplib.

However, not using -Duseshrplib breaks at least one port:  http://trac.macports.org/ticket/23085

This is what the shared variant already does, JFYI. So basically you're asking for this to become the default and there to be a static variant instead?

[reg-macports.org@…]

Oh, sorry. I had not noticed that there already is a variant.

But yes, until ports (like wml) can depend on variants, the most compatible variant should be the default.
