I just wanted to sum this point up (rollback of update-alternatives in 1250 and 
12051):

I found the reason why I could not replace newer build with older ones on 
CentOS and fixed it. I can now reproduce what Enrico also confirmed. I can 
install/uninstall/reinstall any version of ooRexx from 12050 to the current 
12058.

However, trying to install any version prior to 12050 fail. The installation of 
for instance 12038 will go through without any error messages but rexx -v will 
consistently refer to the last install (the install with the highest revision 
number). I have tried it on 3 different .rpm builds and 3 different .deb builds 
and the behavior is the same so I think it is not just me. As a consequence it 
is no longer possible to go back to a version of ooRexx containing the 
rexx-oorexx update-alternatives solution. Further In 12058 I restored some 
variables needed in the installer that were removed by the rollback. The 
package on CentOS is now correctly indicating the revision number which it did 
not do in 12057.

I propose another solution to the update-alternatives problem: Why not provide 
Linux installers for an alternative installation location for those who really 
need it, say to /opt or /usr/local/ rather than to /usr? Such an installation 
would be active only after amending the path, something that could be arranged 
with a shell script. Most Slaves on Jenkins are dormant 90-95% of the time so 
there is capacity for building them.

I also have a question to those juggling several rexx installations: how is it 
done on the Windows platform?
