But those paths should not be used unconditionally (as you have).
They are not right for most x86_64 Linux, Solaris, ... and they
might not even be right on Mac OS X (depending on the X
installation).

Sorry, but I don't known how to find the correct path at compile
time.

Use a configure script: see 'Writing R Extensions' (and see how R
itself does it).

Thanks for the suggestion! I adapted the code from cairoDevice
package. It was just a matter of replacing gtk with x11 and I hope
that now it will build on any unix that have X installed.

Using Mac OS X 10.6.8 and R version 2.15.2 (2012-10-26)

Experiment 1
----------------
[.../vimcom]: R CMD check vimcom-master
* using log directory '/Users/berendhasselman/Documents/Programming/R/pkgsrc/vimcom/vimcom-master.Rcheck'
* using R version 2.15.2 (2012-10-26)
* using platform: x86_64-apple-darwin9.8.0 (64-bit)
* using session charset: UTF-8
* checking for file 'vimcom-master/DESCRIPTION' ... OK
* this is package 'vimcom' version '0.9-5'
* checking package namespace information ... OK
* checking package dependencies ... ERROR
Package suggested but not available: 'knitr'

The suggested packages are required for a complete check.
Checking can be attempted without them by setting the environment
variable _R_CHECK_FORCE_SUGGESTS_ to a false value.

Experiment 2
----------------
[.../vimcom]: export _R_CHECK_FORCE_SUGGESTS_=0
[.../vimcom]: R CMD check vimcom-master
* using log directory '/Users/berendhasselman/Documents/Programming/R/pkgsrc/vimcom/vimcom-master.Rcheck'
* using R version 2.15.2 (2012-10-26)
* using platform: x86_64-apple-darwin9.8.0 (64-bit)
* using session charset: UTF-8
* checking for file 'vimcom-master/DESCRIPTION' ... OK
* this is package 'vimcom' version '0.9-5'
* checking package namespace information ... OK
* checking package dependencies ... NOTE
Package suggested but not available for checking: 'knitr'
* checking if this is a source package ... OK
* checking if there is a namespace ... OK
* checking for executable files ... OK
* checking whether package 'vimcom' can be installed ... ERROR

Install experiment

pkg-config is not available standard on Mac OS X.
It is probably available on the Mac binary package machine.

I don't think you may assume that an X11 installation on Mac OS X has been registered with pkg-config or how you call that.

Your method is not foolproof.
Experts will have to enlighten you.
