> Out of curiosity, looking for files that seemingly without good cause had the extended attribute on them, I noticed that almost all (417 out of 425) of the files installed for port libsdl had it on them (as well as two files for xephem:  /opt/local/share/xephem/auxil/wmm.cof and  /opt/local/share/xephem/lo/lodb.xml).

But it happened consistently on at least two systems, and I didn't do anything particularly strange installing MacPorts on them. But since _most_ ports don't leave that sort of mess around, I'm thinking it shouldn't have happened.

For libsdl it would be a side effect of how I generated the distfile.
It's installing a snapshot of the hg repo because there have been a lot
of important fixes since the last release of the 1.2 branch, and the
next release may be a long way off still (if it ever happens; 1.2 is
only kept around to support projects that haven't moved to SDL2). I
re-made the tarball myself because there is no suitable tarball
available from upstream (the hg web interface generates tarballs that
differ depending on when you generate them, and the directory name is
not what MacPorts expects).

As you say, it shouldn't cause any serious problems, but I'll try to
avoid it in future tarballs.
