As discussed on tech-pkg@ add a Makefile fragment intended to help

packaging RubyGems.
Its functionality is somewhat limited for now but will be without
doubt improved and refactored in the very near future.

+# This Makefile fragment is intended to be included by packages that build
+# and install Ruby gems.
+#
+# The following target is provided by this file:
+#
+# do-gem-install	installed as a dependency of the do-install target
+# 			it install the Ruby Gem ${GEMFILE}.
+#
+# do-build		Mostly phony target, but necessary for various
+# 			pkgsrc framework to work, in case the Gem to install
+# 			contains sources to compile.
+#
+# The following variables may be set prior to including this file:
+#
+# GEM_NAME		The name of the Gem to install, it defaults
+# 			to ${DISTNAME}.
+#
+# GEMFILE		The filename, in ${_DISTDIR}, of the Gem to install.
+#
+# If the Gem to install does not contain sources to compile NO_BUILD
+# should be defined.
+#
+# The name, PKGNAME, of the package installing the Gem should probably
+# use '${RUBYGEM_PKGPREFIX}-' as a prefix.
