Comment (by a.schuster@…):

 Replying to [comment:3 ryandesign@…]:
 > Thanks. Some observations:

 Thanks for your helpful comments! I've attached a revised Portfile.

 >  * The `$Id$` line should not be removed.
 >  * When updating to a new version, the `revision` line should be removed
 or set to 0.
 >  * "universal_variant yes" is the default and does not need to be
 mentioned explicitly.

 done.

 >  * The pcre variant just adds a dependency; that's usually not
 sufficient. The port needs to ensure that the pcre library will ''not'' be
 used if the pcre variant is ''not'' selected.

 Now there's only one variant that enables re2, and at the same time
 disables pcre.
