Thanks Oliver for the 1.5.0 DEB.
I meet the same problem as what I have reported before for 1.4.0. When 
starting (or, rather, not):

The DEB has a requirement for python-yaml and mapproxy installed 
3.09-2build1 on Ubuntu 10.04.
As I explained before, if I remove that requirement from the DEB (and 
uninstall yaml), mapproxy runs fine.

I'm no python specialist and I had found that workaround by intuition.

Would APT (DEB package manager) not be informed that another python-yaml 
is installed?
What command would tell me that?
I guessed a little more and I found this:
$pycentral list | grep yaml  | less

I hope this will explain something to you and help.
Although I have my workaround, I'd prefer to use a standard installation.
