[Mono-dev] Module Heap-buddy not found

[APS]

Hi,

I'm trying to profile a mono 2.0.1 web application.
I launched mod_mono-server2 with 
the  --profile=heap-buddy:/tmp/buddy.out parameter but when I start 
apache service I receive a warning:

** (/usr/local/lib/mono/2.0/mod-mono-server2.exe:23306): WARNING **: 
Error loading profiler module 'mono-profiler-heap-buddy': 
libmono-profiler-heap-buddy.so: cannot open shared object file: No 
such file or directory

and no profile data is collected.
I searched and found the file in 
/usr/local/lib/libmono-profiler-heap-buddy.so together other profilers.
I tried copying it in /usr/lib/libmono-profiler-heap-buddy.so
and I receive another warning

** (/usr/local/lib/mono/2.0/mod-mono-server2.exe:2446): WARNING **: 
Thread (nil) may have been prematurely finalized

What I'm doing wrong?
