the culprit was my colinux kernel (2.6.26.8-co-0.7.7.1) did not have pipe2 support (which libc erronenously assumed). updating the kernel fixed the problem.

the libc issue is partially discussed @ http://www.0x61.com/forum/linux-kernel-f109/popen2-popen-call-t1229012.html.  according to manpage pipe2 was not added to the kernel til 2.6.27

my guess is this affects all unstable debian systems which are running kernels 2.6.26 or older (u decide whether or not using old kernels for debian unstable is an edge case ;)
