[R] problem configuring package udunits

[Prof Brian Ripley]

Please ask the maintainer.  The 'udunits' R package seems to require its 
libraries in particular places.  Note that it is looking for 
/usr/lib/libudunits.a, that is a static library in a 32-bit library 
directory, whereas you most likely have /usr/lib64/libudunits.so or 
/usr/lib64/libudunits.a  (This only works for me because I have both 32- 
and 64-bit versions of udunits installed.)

However, that is if you have udunits installed, since 
/usr/include/udunits.h is missing.  You do need both the udunits and 
udunits-dev packages installed.

On Windows someone else struggled with this badly designed package for 
you.
