net-im/silc-client-1.0.2 does not start compiles fine, first-time use generates a key, but after starting 'silc' the app closes direct
The silc-slk seems to require that the real name of the user is set. ie. the fifth field in passwd. Set the real name and then it works.
fixed in 1.0.3 - version bump request in https://bugs.gentoo.org/show_bug.cgi?id=122848 changes 1.0.3 - empty realname and hostname is permitted again (and the user gets to see the error message if something goes wrong)
As it's bumped in CVS now, marking as FIXED
