I am working on a headless ubuntu machine with most of the cairo requirements preinstalled, but I am stumbling on getting R to use Cairo. Does anyone know what flags or additional packages I need to set/install in order to have install.packages build Cairo correctly with the existing installs of its dependencies? The tricks: I cannot use sudo commands or apt-get, and additional software must involve <50Mb of memory. Is this possible? It looks like most everything I need is present, if I can wire it into R.

Error in library("Cairo") : there is no package called ‘Cairo’

This means I need to install the libcairo2-dev package, but doing so via configure/make runs into a pixman error despite pixman being present on my system:
package pixman-1 was not found in the pkg-config search path.
Perhaps you should add the directory containing `pixman-1.pc'
to the PKG_CONFIG_PATH environment variable
No package 'pixman-1' found
No package 'pixman-1' found
checking whether cairo's image surface backend feature could be enabled
no (requires pixman-1 >= 0.22.0 http://cairographics.org/releases/)error: mandatory image surface backend feature could not be enabled
