Yes, that's correct.

I tried both %%SITE_PERL%% and %%SITE_PERL_REL%% and both failed.

The %%SITE_PERL%% stuff is no longer in pkg-plist.  I moved it to the 
pkg-deinstall script.  I could do some more testing, I suppose.....

OK, commented out one of the modules in the pkg-deinstall script and added 
it to pkg-plist like this:

Then I installed the port and confirmed that the module was installed:
ls /usr/local/lib/perl5/site_perl/5.8.8/mach/

Then I deinstalled the port and got this error:
make deinstall PREFIX=/var/tmp/$(make -V PORTNAME)
===>  Deinstalling for security/bro
===>   Deinstalling bro-1.2
pkg_delete: file '/var/tmp/bro/lib/perl5/site_perl/5.8.8/mach/' 
doesn't exist
pkg_delete: couldn't entirely delete package (perhaps the packing list is
incorrectly specified?)

As you can see, SITE_PERL is prepending PREFIX to SITE_PERL_REL (as you 
said), but perl modules are *always* installed in 
/usr/local/lib/perl5/site_perl/blah, are they not?

IOW, this will work fine in pkg-plist *if* (and only if) PREFIX is the 
default.  If the installer changes PREFIX to anything else, the perl 
modules will not be uninstalled and the deinstall will generate an error. 
(Installing the perl modules in non-standard-PREFIX/lib/blah makes no sense 
because the scripts won't work because @INC doesn't include non-standard 
locations by default.)

Perhaps the correct way to resolve this is to change to define 
${SITE_PERL} in pkg-plist as ${LOCALBASE}/${SITE_PERL_REL} instead of 
${PREFIX}/${SITE_PERL_REL}?  No matter what PREFIX an installer chooses, 
perl modules should always be in LOCALBASE, right?
