Hi Alan,

My test results for pscairo.

Ubuntu edgy
libpango1.0-dev 1.14.5-0ubuntu1
libcairo2-dev 1.2.4-1ubuntu2
Plots appear ok, but the text is tiny to the point of being unreadable.

Ubuntu gutsy (latest stable)
libpango1.0-dev 1.18.3-0ubuntu1
libcairo2-dev 1.4.10-1ubuntu4
A large number of the plots are "missing" parts of the image. Sounds
like the same issues you have with Debian testing - pretty much the same
version.

Doesn't look terribly good.
