Failed build in Anaconda environment

[lumaku]

If the build fails within an Anaconda environment, the problem ifs often because the ld version of the Anaconda environment differs from the system version. The solution is to delete the anaconda ld.

The error looks like this:

  Building wheel for ctc-segmentation (setup.py) ... error
