This update is an attempt to fix a bug preventing the package from loading under OS X and Linux. Not yet tested, as there seem to be additional problems under OS X at least. At least one remaining problem seems to be related to some component of OmniDriver being incompatible with OS X.
This is an interim patch which will be replaced in due time with a version tested under multiple OSs rather than only under Windows 10.
This package can be downloaded from the repository at this site, not from CRAN. It has system prerequisites described in the documentation.
