Bugzilla Bug 76251

I installed xorg-x11 with USE=minimal, which means the Xvfb support is not
installed.  Because of this, evolution 2.0.3 will not compile.

        Evolution has been configured as follows:

        Mail Directory:   /var/spool/mail, writable by group mail
        LDAP support:     yes (dynamic)
        Pilot conduits:   no
        Kerberos 4/5:     no/no
        SSL support:      yes (Mozilla NSS)
        SMIME support:    yes (Mozilla NSS)
        IPv6 support:     no
        Dot Locking:      yes
        File Locking:     fcntl
        Gtk-doc:          no

        Programming documentation files will not be built.
        You may want to install the gtk-doc package
        so that you will get the Evolution Developer's Guide.

These are the packages that I would merge, in order:

we dont maintain the eclass, we don't control the x11 minimal build.

Well, the problem is that the X minimal build does not come with Xvfb, which
the evolution build should not be relying on anyway, as it might not always be
present.

The offending part of the evolution ebuild is here:

    # Needs to be able to connect to X display to build.
    Xemake || Xmake || die "make failed"

It obviously is a problem with the virtualmake function under the
virtualx.eclass

Is there any way I can force the build to work (set DISPLAY=localhost:0) ?

Problem confirmed. Changing Severity to a blocker as this prevents people from
upgrading evolution which has a serious security bug open.

bug #79183

Xemake/Xmake is officially a hangover from the pre-1.2 days. The current
versions (2.0.x) compile fine with "emake || die "emake failed"", both in and
out of an X session.

Al, can you verify and fix in the next day or so? otherwise I'll commit the
changes to the 2.0.x ebuilds.

Thanks.

I hacked around it by doing this in the virtualx.eclass. 

-	if [ -z "$DISPLAY" ] || ! (/usr/X11R6/bin/xhost &>/dev/null)
+	#if [ -z "$DISPLAY" ] || ! (/usr/X11R6/bin/xhost &>/dev/null)
+	if false

Then evolution then built fine.

yep, i'll do some testing this afternoon GMT

removed virtualx/xemake from the latest 2.0.2-r1 and 2.0.3-r1
