[R-SIG-Mac] RGnumeric plugin

[Simon Urbanek]

Jacob,

I didn't check RGnumeric (since I don't use Gnumeric), but just some 
general answers:

Yes and it's the default on Mac OS X.

You current installation is already build as a shared library and it is 
located (if you used the CRAN installer) in 
/Library/Frameworks/R.framework/Resources/lib/libR.dylib. If RGnumeric 
uses a smart configure script, it should detect the shared library 
easily. If it's not as smart (or outdated - note that since 2.0 the 
shared library is in $R_HOME/lib instead of previously $R_HOME/bin), 
you may need to set some compiler flags.

Cheers,
Simon
