Because some of the libgxim headers were renamed in version 0.4.0, the official ebuild for imsettings-1.5 doesn't actually build properly, and runs into this error while emerging:
loopback.c:36:33: fatal error: libgxim/gximmessage.h: No such file or directory
It looks like there has already been a fix for this committed upstream at https://bitbucket.org/tagoh/imsettings/commits/f45bd0f5e5ed2b5fb8831e8af0fc101199c26fd2?at=1.5.1 , and is available in the next version up: 1.5.1, which contains a few trivial fixes and cleanups. I've updated the ebuild for 1.5.1 and attached it to the bug report.
There never was a =x11-libs/libgxim-0.4.0.
