# 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.
#

# Include this early in case some of its target are needed
.include "../../lang/ruby/modules.mk"

# Build and run-time dependency on rubygem
#
# We need rubygems>=1.0.1nb1 to actually build the package, but the
# resulting installed gem can run with older versions of rubygems.
