[Pp]honon & QCA issue in KDE ports

[Michael Dickens]

I think adding a couple bits of code to the KDE group file make sense,
and I'm wondering what others think. - MLD

(1) I've encountered 3 KDE ports now that use #include <Phonon...>
instead of #include <phonon...>.  For those of us who use a
case-sensitive file system, installing this port will generate an error
since Qt 4.6.3 (and 4.7.0b's) install them as the latter.  For now, I've
added a quick patch routine to those ports' Portfile to do a
'reinplace'.  A quick internet search of "#include phonon" reveals that
both ways (P and p) are used regularly -- so, I'm tempted to add in this
patch routine to the overall kde group.  Right now, the patch looks
like:

post-extract {
    # change #include ...Phonon... to ...phonon... in all files that
    # contain that header.
    foreach item [exec grep -lr "Phonon" ${workpath}/${distname}] {
        reinplace "/#include/s at Phonon@phonon@" ${item}
    }
}

but I know that if 'grep' finds nothing it will generate an error (which
is undesirable); hence this patch isn't correct for -all- KDE ports,
just those that need it.  I can do a 'fs-traverse' but that seems
wasteful (though it certainly would work & make for concise coding).

(2) Along the same lines, even though the KDE group specifies (for now)
the 'qt4-mac' Port and the specific location of 'qmake', if any other
ports have installed themselves into the Qt4 area (e.g., QCA) then their
info will not be picked up unless

configure.pkg_config_path-append ${qt_dir}/lib/pkgconfig

is added to the Portfile (hard-wiring the library is dangerous, since
most can be installed as library or framework).  Seems like this line is
generic enough to add to the KDE group file.
