Hi, Per

Those libs seem to come from 

Requires: glib-2.0 gmodule-no-export-2.0

entry in upstream enchant.pc.in

I guess you mean that lyx can use enchant without explicitly depending on
above libraries, enchant itself seems to heavily rely on glib-2.0.

I am not familiar with pkg-config and friends. Should something like
Requires.private help here? Or is better Libs.private as you suggest?

PS: I am not enchant maintainer, just have it under my radar because I
uploaded last QA. enchant itself is orphaned.
