Hmmm, I have checked
   https://buildd.debian.org/status/package.php?p=python-skbio
before I started to investigate time into this and it says `uncompiled`
for the 32bit architectures.

I admit the 0.5.8-2 has migrated which I did not expected since when
I was looking excuses contained those build problems.

Thanks for the additional hints (and have a nice trip).

Kind regards
