R SIG Fedora - Jun 2008 - Pango/cairo and symbol fonts

Excuse my asking here than on R-help, but it may be a Fedora question. On 
Fedora 7, I'm running a fresh R 2.7.1 built from source, usually in en_GB, 
but also tried in en_GB.UTF8. Running example(plotmath) generates lots of:

Pango-WARNING **: shape engine failure, expect ugly output. the offending 
font is 'Symbol Not-Rotated ...'

Setting:

x11(type="Xlib")

relieves the problem, but I'd like to use cairo if possible. I have both 
urw-fonts and liberation-fonts installed. I'm pretty sure it is my F7, not 
R, and would be grateful for any advice. It's the same story with the png 
device.

Roger,

Check capabilities() to be sure that 'cairo' shows as TRUE.

If it shows FALSE, be sure to install the cairo and cairo-devel RPMs and 
re-build R so that cairo support is available. You may just need the 
'cairo-devel' RPM if the 'cairo' RPM is already present.

Also, as an aside, F7 went EOL on June 13.

If that is not helpful, post back.

Marc
