Importing the multiarray numpy extension module failed. Most
likely you are trying to import a failed build of numpy.
If you're working with a numpy git repo, try `git clean -xdf` (removes all
files not under version control). Otherwise reinstall numpy.
Original error was: /usr/local/lib/libblas.so.2: Undefined symbol

I have used a portsnap generated ports tree for the first build.
I have built all ports from this ports tree, no updates of the ports tree.
To be sure I have checked out a new ports tree using svnlite:
root@wqtest:/usr/local/BUILD/Poudriere-current12/ports/svn # svnlite info

Using this new ports tree I tried to build ports-mgmt/porttree,
I got the same errors.
