Comment:

 You should disable building the perl module, because you don't know for
 which perl it will be built. (It would depend on which variant of the
 perl5 port the user has selected.) If someone actually needs the perl
 module, it can be reintroduced later as a p5-udunits port with subports
 for each supported version of perl.

 According to the INSTALL file, the way to disable the perl module is to
 set the environment variable `PERL` to the empty string. Doing this causes
 a new message to appear during configure:

 {{{
 ./configure: ERROR: The following variables need values:

 VARIABLE     DESCRIPTION                EXAMPLE
 --------     -------                    -------
 LD_YACC      yacc library               -ly
 }}}

 The INSTALL file does not explain this option, but simply adding
 `LD_YACC=-ly` to the environment as well allowed the build to succeed for
 me on OS X 10.8. Patch attached.
