qwt does not build with new qt4-mac port

[BSeppke (Benjamin Seppke)]

Since the qt4-mac port has recently/eventually received a major update. All of my dependent ports are building nicely except qwt-*. I tried qwt, qwt60 and qwt-devel and am always getting the follwing error at the staging phase:

---> Staging qwt-devel into destroot Error: org.macports.destroot for port qwt-devel returned: symlink: /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_graphics_qwt/qwt-devel/work/destroot/opt/local/libexec/qt4/include/qwt -> /opt/local/libexec/qt4/Library/Frameworks/qwt.framework/Headers: no such file or directory

Since this exactly describes the error, I will not post the entire log here.

A possible solution (for me at least) was to remove the post-destroot stage inside the port file - although I'm quite unsure if that is okay or needed somewhere else.
