[Zope] Zope install after compiling

[Thyb]

Hi,

I encountered an error during installing a successfuly compiled zope.

copying skel/var/README.txt -> /opt/Zope-2.7/lib/python/../../skel/var
        [ -f /opt/Zope-2.7/bin/python ] || ln -sfn
"/usr/local/bin/python" /opt/Zope-2.7/bin/python
Usage: ln [-f|n] [-s] src [target]
   or: ln [-f|n] [-s] src1 ... srcN directory
make: 1254-004 The error code from the last command is 1.

Why did this happen?
