Cannot compile the SVN version

[pplive]

Dear all,
I just downloaded the svn version of WANProxy, and tried to "make" it.
However, I cannot compile it. The error information is as follows (my
system is Ubuntu 10.04) :
/../../../event/event_poll_select.cc

Can someone provide me some hint? Thanks so much!
