Peter,
the changes you made should be ok. (No changes are needed for gcc/g++
anyway.) The problem is not the C compiler, which is (most likely)
gcc, but the c++ compiler, which is not the GNU
c++ compiler, but the Sun version. I guess that the GNU c++ compiler
is called g++ or gxx. If you found out which one, or that this
compiler is installed on your system at all, see
6.3.3 in http://cran.r-project.org/doc/manuals/R-admin.pdf
on how to supply your Makevars file.
--configure-args might work as well, but you need to set the
CXX variable, not CC.
My understanding is that once you set up gcc/g++ in your Makevars file,
you can simply do 'install.packages("igraph")'.
Someone who knows Solaris/R better, please correct me if i'm wrong.
