-RM-103-MR-[unittest_WReaderEEGASCII] Building OW in Ubuntu 11.10 (oneiric) with tests fails.

Searching for the @cholmod_start@ symbol inside biosig gives:

> nm -D `locate libbiosig.so` | grep cholmod_start
      U cholmod_start
      U cholmod_start
      U cholmod_start

There was a similar problem with @sigviewer@ described at: https://bugs.launchpad.net/ubuntu/+source/sigviewer/+bug/803196. But the solution was not obvious.
