Created attachment 401762 [details] tail of build failure illustrating error In perhaps a progression of bug #461480, recent 1.2.0_rc2 and above versions of net-misc/remmina will not build with USE='ssh -vte' (the natural state of USE flags). Please consider combining them or enabling them both by default.
I somehow missed bug #546886 in my search and will defer to the earlier filing. I should also note that USE="ssh" is not the default/natural state, but an apparently fairly typical one.
