This version is requiring a too old boost, so it's masked. Consider whether you should just drop the keyword (and thus the ebuild) or if you want to fasttrack a newer version in. No I have no idea how comes there wasn't a keywordreq bug.
Okay things should be all fixed now: 1) visual-5.74 was rapid keyworded/stabilized along with its dep dev-python/polygon-2.0.4. 2) visual-5.4 with its broken dep on <boost-1.48 is off the tree Note: visual-5.72-r2 did not build on ppc, so I could not keyword/stabilize it, at least not rapidly. If it should be, the python herd can open a bug and I'll post the error. If they are okwy with what I've done, all the better.
