There is no "collector.so". There is a "libcollector.so" which
is required for collecting data, whether through dbx or collect.
It is installed in .../prod/lib/dbxruntime and.../prod/lib/dbxruntime/sparcv9
It is installed in the package SPROprfan and SPROprfax on
Solaris. The former is 32-bit, and the latter is 64-bit. You'll
probably also want SPROprfgn (the Analyzer GUI),
and SPROprflb and SPROprflx, the 32- and 64-bit packaged
with the user API (man libcollector).
