problems with pgp 5i for solaris

I am having problems with PGP 5i for solaris. I am aware of http://www.pgpi.com/bugs/bugs50i.shtml I have tried setting HAVE64 to 0 and the *** src/lib/pgp/include/pgpUsuals.h~ Sat Aug 9 22:44:58 1997 --- src/lib/pgp/include/pgpUsuals.h Tue Aug 12 16:57:16 1997 patch but neither solve my problem. I get "Received signal 10." after entering my pass phrase when trying to decrypt a message encoded to my PK. Has anyone got it to work? -- pgp 1024/D9C69DF9 1997/10/14 steve mynott
