Hi,

I am trying to get the R package Cairo installed. I've been successfully in
building the latest version of Cairo library (1.12.16,
http://cairographics.org/) from source and installed into ~/usr/local using

./configure --prefix=/home/fong/usr/local

I set the my CAIRO_LIBS and CAIRO_CLAGS environment variables in my
~/.bashrc:

export CAIRO_LIBS=${HOME}/usr/local/lib
export CAIRO_CFLAGS=${HOME}/usr/local/include

When I try to install Cairo in R using:

install.packages('Cairo')

I get the following error:

checking for pkg-config... /home/fong/usr/local/bin/pkg-config
configure: CAIRO_CFLAGS=/home/fong/usr/local/include/cairo
checking if R was compiled with the RConn patch... no
checking cairo.h usability... no
checking cairo.h presence... no
checking for cairo.h... no
configure: error: Cannot find cairo.h! Please install cairo (
http://www.cairographics.org/) and/or set CAIRO_CFLAGS/LIBS correspondingly.
ERROR: configuration failed for package 'Cairo'

But I can see the cairo.h header in /home/fong/usr/local/include/cairo. I
been trying to scouring the internet for answers, but I can't seem to find
any work for me. If anyone has any suggestions that would be helpful.

Thanks
