Miro 2.0.4 won't compile on Centos 5.3

Hi

I tried to get Miro on my Centos 5.3 box, but so far without luck. When I try to compile the source for 2.0.4 I get

peer_plugin.cpp:130: error: ‘len’ was not declared in this scope
error: command 'gcc' failed with exit status 1

Any idea what's missing?

The complete output follows:
libtorrent-rasterbar not installed on this system.
