You can also use the "ldd" command to list the specific shlibs linked by a program, but you can usually assume that if it's dynamically linked, it has dynamically linked all its libraries too. Theoretically, a program could have linked directly to /usr/lib/libssl.a, but most of the time they just use -lssl, which will prefer shared libraries over static. -- Dan Nelson dnelson@allantgroup.com
