[R-SIG-Mac] The Equivalent of pkg-config for Frameworks

[Dominic Steinitz]

My googling skills are failing. I want to install a package which relies on R. This currently works on windows and linux. When I try it on my macbook I get told

> Configuring H-0.1.0.0... 
> Warning: Instead of 'ghc-options: -cpp' use 'extensions: CPP' 
> cabal: The pkg-config package 'libR' version >=3.0 is required but it

> cabal: Error: some packages failed to install: 
> H-0.1.0.0 failed during the configure step. The exception was: 
> ExitFailure 1 

But I have R installed

> $ R --version 
> R version 3.0.2 (2013-09-25) -- "Frisbee Sailing" 
> Copyright (C) 2013 The R Foundation for Statistical Computing

It seems the installer for the package uses pkg-config to check for the existence of R.

> $ pkg-config --version
> 0.28


It finds e.g. the gnu scientific library

> $ pkg-config  --libs gsl
> -L/usr/local/Cellar/gsl/1.16/lib -lgsl -lgslcblas -lm


But can’t find R

> $ pkg-config  --libs R
> Package R was not found in the pkg-config search path.
> Perhaps you should add the directory containing `R.pc'
> to the PKG_CONFIG_PATH environment variable
> No package 'R' found


On my installation, R lives in

> /Library/Frameworks/R.framework

In order to use pkg-config, it seems I need a .pc file somewhere but I can’t find one.

Can someone either tell me where the .pc file is for R or alternatively how to tell the installer where to find R?

Many thanks
