Just a side note: it's not a good idea to patch configure, since it is 
auto-generated from configure.ac
You probably want to use following patch for configure.ac: (this one is 
based on current R-devel, but that should be no problem)

Of course you'll need to re-run autoconf after patching.
Again, this is untested since I have no OpenBSD box here.

Cheers,
