Unable to create PNG files using R

when I try to create png files using R in linux platfrom, my R window hangs. I try to search google about possible causes, but answer. I install Cairio package for R. Has anybody seen this issue?

This is the session info:

> library(Cairo)
> sessionInfo()
R version 2.14.2 (2012-02-29)
Platform: x86_64-unknown-linux-gnu (64-bit)

locale:
[1] C

attached base packages:
[1] stats     graphics  grDevices utils     datasets  methods   base     

other attached packages:
[1] Cairo_1.5-1
> x<-1:100
> png(filename = "Rplot%03d.png", width = 480, height = 480,
+ )

at this point, it hangs

Look at capabilities() and see if it lists PNG:

> capabilities()
    jpeg      png     tiff    tcltk      X11     aqua http/ftp  sockets   libxml 
    TRUE     TRUE     TRUE     TRUE     TRUE    FALSE     TRUE     TRUE     TRUE 
    fifo   cledit    iconv      NLS  profmem    cairo 
    TRUE     TRUE     TRUE     TRUE     TRUE     TRUE

That's on my Ubuntu machine using the pre-built binary from Michael's repo (mirrored on CRAN) using the Debian package I maintain. We make sure that just about everything that can be provided is provided -- aqua is Mac-only.
