My google searches result in some possible causes for a behaviour like this, but none of them matches my case. :(

1. DOS line endings -> checked: none

2. noexec mount option -> checked: exec

3. acl or user_xattr effects -> checked: not used

Looking into the logs and playing with the devshell i found these interesting points:

This is perl, v5.8.8 built for i686-linux-thread-multi
...

So the perl interpreter seems not to be the problem. Confusing for me is the original error message:

"/home/DRESEARCH/production/METABUILD/2009-08-03-15-24-27--hydraip-build--28595: bad interpreter: Permission denied"

I would expect something like:

"/home/DRESEARCH/production/METABUILD/2009-08-03-15-24-27--hydraip-build--28595/OpenEmbedded/tmp.3/staging/i686-linux/usr/bin/pod2man: bad interpreter: Permission denied"

It looks like someone cut the path to the pod2man script.

I would be really grateful for some help.
