The parole source contains the API headers for mozilla plugins, and therefore does not need to depend on net-libs/xulrunner when the "nsplugin" USE flag is enabled. Moreover, nowhere in the documentation is this dependency mentioned. I edited the ebuild to remove this dependency and emerged parole with "nsplugin" in my USE flags, and it works fine with Midori.
(In reply to comment #0) > enabled. Moreover, nowhere in the documentation is this dependency mentioned. Hmm, correct you are there. The only mention of xulrunner is in the NEWS file. %% grep -ri xulrunner * NEWS:- Fix compilation with xulrunner 1.9.2. I wonder what that means. Anyway, it will be quite awhile before I have a chance to test this, maybe someone else can check it in the meantime.
just checked, looks like it works without xulrunner
