You should just do "PKG_OPTIONS.rt=pgsql modperl1".  You never need to
specify the group names, they're internal to the pkgsr infrastructure.  See
for example the output of "make show-options", it doesn't mention the group
names either (in principle you never have to look at the Makefile code to
figure out how to use a package).  

The only consequence of groups is that you cannot specify more than one
option of any group at the same time, and for required groups, you have to
specify at least one.
