Right, that fixes one problem but we are not done yet.

Now ssh-agent correctly dlopen /usr/pkg/lib/opensc-pkcs11.so, which in
turns dlopen libopensc.so (no problem), which then attemps to dlopen
libpscslite.so and here we break again because it is linked with -lpthread

$ ldd /usr/pkg/lib/libpcsclite.so
/usr/pkg/lib/libpcsclite.so:
        -lpthread.1 => /usr/lib/libpthread.so.1
        -lgcc_s.1 => /usr/lib/libgcc_s.so.1
        -lc.12 => /usr/lib/libc.so.12

But this time, threads are really used:

$ nm /usr/pkg/lib/libpcsclite.so|grep pthread_ 
         U pthread_attr_destroy
         U pthread_attr_init
         U pthread_attr_setdetachstate
         U pthread_cancel
         U pthread_create
         U pthread_detach
         U pthread_join
         U pthread_setcanceltype
