Dear guys,
thanks to Stephane i solved this problem.
After running ldconfig, i solved the problem of undefined symbol but i got this problem (i'm using an external usb M-AUDIO card):
/usr/local/bin/jackd -R -P89 -t1000 -m -dalsa -r44100 -p128 -n3 -D -Chw:0,1 -Phw:0,0 -Xseq -H -M
.
.
.

Acquire audio card Audio0

Failed to acquire device: Input/output error

Error playback audio device hw:0,0 not available...

Cannot initialize driver

no message buffer overruns

JackServer::Open() failed with -1

Write server and clients timing data...

Failed to start server

Always thanks to Stephane, i installed the svn version and fixed also that problem. Now it works perfectly. I hope to help you in the future.

Cheers,

Marco

"sudo ldconfig" then starting again should solve the problem.
