This seems really weird. Firstly, doesn't OpenBSD use ELF? Shouldn't
the library pull in the indirectly needed libraries automatically? But
more to the point, why on *earth* would com_err depend on -lssl and
-lcrypto? com_err is just a standard error handling library. Why
would it fail to link without ssl and crypto libraries?!?!

If it is necessary, putting in an "if portname = openbsd" is defeating
the whole purpose of using autoconf here. Surely something like

   AC_SEARCH_LIBS(com_err, [krb5 'krb5 -lcrypto -ldes -lasn1 -lroken'
'com_err' 'com_err -lssl -lcrypto'], [],

would be better since it would detect this situation regardless of
what OS it's on.
