Bugzilla Bug 84497

The following line in the src_unpack() function of the current ebuild:

        use gtk2 && epatch ${FILESDIR}/${PN}-gtk2.patch || die "patch failed"

should be modified to:

        use gtk2 && (epatch ${FILESDIR}/${PN}-gtk2.patch || die "patch failed")

Otherwise the ebuild will unconditionally die with "patch failed" when not compiling with the gtk2 USE flag.

Reproducible: Always
Steps to Reproduce:
1. USE="-gtk2" emerge mupen64-riceplugin
2.
3.

Actual Results:  
>>> emerge (1 of 1) games-emulation/mupen64-riceplugin-5.1.0 to / 
>>> md5 src_uri ;-) riceplugin.tar.bz2 
>>> Unpacking source... 
>>> Unpacking riceplugin.tar.bz2

 * Applying mupen64-riceplugin-makefile.patch ...

Actually, it should be:

if use gtk2; then
    epatch ${FILESDIR}/${PN}-gtk2.patch || die "patch failed"
fi

fixed in portage, allow one hour to sync

thank you for reporting this
