[Tikzdevice-bugs] tikz() fails

[baptiste auguie]

Hi,

I can't seem to get tikzDevice to work on my machine. I tried the CRAN 
version, the r-forge version, and even github. I get this error message,

library(tikzDevice)
Loading required package: filehash
filehash: Simple key-value database (2.2 2011-07-21)

loaded via a namespace (and not attached):

Any ideas what could be wrong with my setup?

Thanks,
