This is the same issue as bug #498810, which seems to have not been fully fixed. Note this only happens with sys-libs/ncurses[tinfo].

Created attachment 394418 [details, diff] cscope-15.8a-r1.ebuild.diff "$(tc-getPKG_CONFIG)" --libs ncurses expands to: -lncurses -ltinfo (with sys-libs/ncurses[tinfo]), so the substitution should be quoted. This fixes the issue on my machine. (While we're at it, it seems the ebuild would be suitable for a bump to EAPI=5.)
Also, this should probably block #457530.
Fixed without revbump, since this is a build failure. Thank you for reporting. (In reply to Quentin Minster from comment #1) > (While we're at it, it seems the ebuild would be suitable for a bump to > EAPI=5.) Will be done with the next version or revision bump.
Thank you very much!
