Is that really cryptlib 3.1.x from 11 years ago?  That's been out of support for
years, it looks like there's an old copy of 3.1 b5 at:

ftp://rinet.tucows.com/pub/FreeBSD-Archive/ports/i386/packages-5.2-release/All/cryptlib-3.1.b5.tbz

but if the key was generated with 3.1 it implies it's more than a decade old.
If you want to read the file with 3.4.x you could put a breakpoint in
keyset/pkcs15_getp.c, line 814, the call:

    status = krnlSendMessage( SYSTEM_OBJECT_HANDLE, IMESSAGE_DEV_IMPORT,
                              &mechanismInfo, MECHANISM_PRIVATEKEYWRAP );

and see where the error is coming from, with a key that old it's hard to tell
what the issue could be.
