I'm using an ancient ptxdist, but that doesn't matter because I'm isolating the SED-version check.

If I run the regex from http://git.pengutronix.de/?p=ptxdist.git;a=blob;f=configure.ac;h=22c8df03a8c225514a3df7ba4c9fb29c515c3e24;hb=HEAD
sed --version 2>/dev/null | sed -ne "1 s/.*GNU.*\s\([[0-9\+\.]]\+\).*/\1/p" then it returns empty, both with sed 4.2.1 and 4.2.2.

Which version of ptxdist are you using?

I think the problem has been fixed with the patch:

    2a89985 configure.ac: change regex for sed version

AFAIK we don't have any problems with sed since the above patch in
mainline, which is ptxdist-2013.01.0.
