make failure on OS X 10.7.4 -- possible to compile on OS X?

[jozefl]

Hi, all.

I'm trying to build r-node on a mac, and I'd appreciate any assistance anyone can offer. I've run into the problem that R.app stores its libraries in different locations.  I already edited the server/Makefile per some of Jamie's suggestions, so now when I try to make, it can, for example, find node. But I'm running into a problem that seems to be with setting the path to the core library with LDFLAGS. libR.dylib is located at:

/Library/Frameworks/R.framework/Versions/2.15/Resources/lib

So the LDFLAGS and CPPFLAGS of my edited makefile look like:

LDFLAGS = -shared -L/Library/Frameworks/R.framework/Versions/2.15/Resources/lib -lR

CPPFLAGS = -I/usr/local/include/node -Isrc/include -DPIC -fPIC -g -c -DEV_MULTIPLICITY=0

And I get the error: "ld: symbol(s) not found for architecture x86_64"

I've put the full output of make below. Any help would be greatly appreciated, even if it's to let me know it can't be compiled on OS X.

Thanks!
