So basically you're asking for this to become the default and there to be a static variant instead? -- Ticket URL: <http://trac.macports.org/ticket/23089#comment:2> MacPorts <http://www.macports.org/> Ports system for Mac OS

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
