Comment (by Ionic):

 Uh, I totally missed that, but generally I don't see a huge benefit to
 depending upon openldap for GPG.

 I've never needed it on my Linux-based systems, but then again I've never
 used LDAP to begin with.

 To be fair, the problem discussed in this PR seems to stem from the
 openldap port *and* a non-standard installation, so I can see why Jan was
 reluctant to change anything in the gnupg port. If the openldap port
 breaks, that one should be fixed.

 But, as said, I also don't see a huge benefit in having the OpenLDAP-
 integration within gnupg. If this taints redistribution, even worse.


 Variants are definitely a two-sided sword. They are both powerful, but
 also too powerful (well, that's really a shortcoming of Portfiles being
 TCL scripts), but any non-standard variant will also make people have to
 build software on their machines instead of using pre-built packages,
 mostly due to combinatorial explosion. I.e., for n variants, there are 2^n
 possible combinations, which would be crazy to build.

 I'd be in favor of making the OpenLDAP-integration fully optional.
