Hi Matthias

Thanks for your reply.

 From x11/qt4-tools/buildlink3.mk:

...
# the way the spec files are currently instealled via pkgsrc, they
# are all identical anyway, so just pick one and point to it.
# Without specifying QMAKESPEC, qmake can't figure it out on some
# platforms (solaris for example)
CONFIGURE_ENV+=         QMAKESPEC=${QTDIR}/mkspecs/netbsd-g++
MAKE_ENV+=              QMAKESPEC=${QTDIR}/mkspecs/netbsd-g++
...

Also qmake on DragonFly defaults to mkspec "freebsd-g++" but pkgsrc sets 
it to "netbsd-g++" when i build wip/qtcreator here.

Actually i don't see where Makefile.common is pulled in through the 
buildlink3.mk chain - i thought Makefile.common is used for qt4 only, 
not for depending packages?

Ok, so this means that we could also abandon this portability hack in 
the qtcreator build system completely and make patch-ae patch it away. 
Looks like we are fine with that anyway, it's more about what solution 
to advertise upstreams. Seems to me that the portability hack they put 
in was just a fix for some bad qmake configurations in the first place.

The advantage of using "${FIND} -exec ${INSTALL_DATA}" is that owner and 
mode are set accordingly, thus i opt to stick with this method unless 
there is reason against it.

AFAIK DragonFly has a similar problem, but i don't think that's a reason 
not to make the Debugging Helper library build. In fact it's just a 
wrapper for gdb output to display Qt4 objects nicely.


If these issues are ok i will try to fix the Debugging Helper library 
and ask for a review on the mailing list later this week.
