A new pcmanfm version (0.4.1.1) is out and since there’s no ebuild yet available I made one by modifying a bit the one I found about version 0.3.2.2 on sunrise overlay. I’ve included a patch I found about enabling/disabling deletion confirmations.
tested on x86 and ppc (thanks to comzeradd)
P.S. Looks like I didn’t search that well on bugzilla, there are other ebuilds there too: http://bugs.gentoo.org/show_bug.cgi?id=121902
