[cairo] No fonts control on Cairo in batch mode

[Christian Kamenik]

Dear all,

I am using Cairo version 1.4-5 for plotting graphs from within R on a 
Gentoo system that does not have X11 installed. I have full control on 
the fonts when running R in interactive mode. But when running R in 
batch mode I cannot change e.g. font size. Letters (including symbols) 
are, however, drawn.

I am exporting the following environmental variables when running R in 
batch mode to point to pkgconfig, which (like Cairo) I installed in a 
non-standard local.

export PATH="$HOME/software/bin:$PATH"
PKG_CONFIG_PATH=$HOME/software/lib/pkgconfig
LD_LIBRARY_PATH=$HOME/software/lib
export PKG_CONFIG_PATH LD_LIBRARY_PATH

Any help would be highly appreciated, Christian
