problems building sm_free3

When trying to build the sm_free3 library on Solaris 7 using gcc 2.95.2 I
get the following errors:

/usr/local/sparc-sun-solaris2.7/bin/ld: ../../lib/sm_free3DLL.so: undefined
versioned symbol name des_encrypt1@@SUNWprivate_1.1
/usr/local/sparc-sun-solaris2.7/bin/ld: failed to set dynamic section sizes:
Bad value
collect2: ld returned 1 exit status
make: *** [dynamiclinkPKCS12] Error 1

How can I get around this error?
