Can you please have a look if virtual/awk is sufficient or if gawk is needed.
the depends in this ebuild are dumb. i've dropped them all. packages should not be depending on awk as that is a @system target.
should be all set now in the tree; thanks for the report! Commit message: Update to EAPI=4 and drop useless depends http://sources.gentoo.org/dev-embedded/jtag/jtag-0.5.1-r1.ebuild?r1=1.5&r2=1.6
