That's exactly what I did. When I saw that it was going to INSTALL
perl5 instead of UPDATE it, I refused to proceed and asked a question
here.

Nice to know, thank you.

I think that is what happened in the log below, but could you explain
it in greater detail? The messages are not entirely self-explanatory.
The (r) and (l) are probably (r)emote and (l)ocal? Whence this conflict
between identical versions of php5-ldap-5.4.39 ?

Conflicts with the existing packages have been found.
One more solver iteration is needed to resolve them.

My repository is public and is located at http://svn64.sibptus.ru 

The build logs are at http://svn64.sibptus.ru:8060/ (I promise to tell
the access credentials to anyone in a private e-mail).
