--------------------+------------------------
 I'm facing difficulty in installing ipopt as a R Package. I get the
 following error:

 * installing *source* package 'ipoptr' ...

 For some reason, the IpJournalist.cpp can't find stdio.h and string.h
 headers. Any clues why this may be so and how this could be fixed?
