Which version of compiler do you use? ( $cc -V)

Pls. check you have sunperf lib installed at <path-to-sun-studio>/prod/lib/amd64. For example,

bash-3.00$ ls -l /opt/SUNWspro/prod/lib/amd64/libsunperf.so*

lrwxrwxrwx1 rootother 15 Sep 22 2006 /opt/SUNWspro/prod/lib/amd64/libsunperf.so -> libsunperf.so.1
