databases/postgresql90-contrib fails to build

[Rainer Hurling]

When I try to build databases/postgresql90-contrib, it stops with not 
finding the right uuid lib:

#cd /usr/ports/databases/databases/postgresql90-contrib
# make

Please report the problem to girgen at FreeBSD.org [maintainer] and attach the
"/usr/ports/databases/postgresql90-contrib/work/postgresql-9.0.5/config.log"
including the output of the failure of your make command. Also, it might be
a good idea to provide an overview of all packages installed on your system
(e.g. an `ls /var/db/pkg`).
*** Error code 1


Obviously the port would like to have misc/ossp-uuid installed. But this 
conflicts with misc/e2fsprogs-libuuid, which was installed by KDE4.

An old PR http://www.freebsd.org/cgi/query-pr.cgi?pr=ports/121745 shows 
some more complexity with this issue. There Jørgen Kjærsgaard told about 
a possible solution, but the PR was reopened in December 2009.

Is there anybody working on this or is there a workaround?

Thanks in advance,
