New description:
on Windows 7 tar does not unpack cddlib spkg correctly, symbolic
links get broken. See

A remedy is to replace them with files, i.e. use tar with -h option to
recreate the spkg---on a machine where tar works, certainly. Works for me.
Something along the following
lines:
{{{
/* on a Unix, with good tar: */
$ tar xjf foo.spkg
$ tar chjf foo.spkg foo/
$ tar xjf foo.spkg
$ sage -spkg foo
$ scp foo.spkg win7cygwinhost:/sageroot/spkg/standard/
}}}
affected packages: cddlib, networkx (and maybe more)
----
New spkg available at [http://sage.math.washington.edu/home/kcrisman
/cddlib-094f.p9.spkg cddlib-094f.p9.spkg].

Replying to [comment:12 kcrisman]:
> I've still never seen this on networkx.

> I think that it would be enough to fix this issue to do the spkg this
special way ONCE and then from then on just make sure there are build
instructions to this effect in the spkg. My spkg doesn't have any changes
like that, so this is not ready for review.
Cygwin developers finally managed to reproduce the problem:
http://permalink.gmane.org/gmane.os.cygwin/127433
it boils down to a bug/feature introduced in 1.7.9, and not really related
to tar itself; so apparently it will be fixed soon.
