Yes, according to the /Solaris Linker and Libraries Guide/ (1995) I happen =
to have lying around, ld does Solaris/SysV versiong, which involves embeddi=
ng version symbols specified in a map file (being generated by GCC in this =
case) into the shared object.

As Viktor wrote, look at what's in test/p_minimal.ld. It should have entrie=
s that look something like this:

        FOO_1.2 {
                global:
                        foo;
        } FOO_1.1;
        FOO_1.1 {
                global:
                        bar;
                local:
                        *;
        };

(or possibly something simpler, or much more complicated). That means "vers=
ion 1.1 publishes symbol 'bar' as part of its interface, and version 1.2 in=
herits the 1.1 interface and adds symbol 'foo'". (I think that's right; it'=
s been years since I looked at this stuff. People rarely use it directly; m=
ostly they just use SVR4 library-name versioning, like having libfoo.so.1 s=
ymlinked as libfoo.so.)

You could also try adding -Wl,'-z noversion' (with the quotes) to the compi=
lation command, to suppress versioning. The book mentions that as an option=
 to ld.

There should be a utility named pvs(1) on the system which you can use to q=
uery version information in shared objects. You might see what it has to sa=
y about your libcrypto and libssl.
