I think there is a problem in recent devel builds of R on Windows with various devices from the grDevices package. For example:

> capabilities()

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

> jpeg()

Error in jpeg() : unable to start jpeg() device In addition: Warning messages:
1: In jpeg() : Unable to load Rbitmap.dll 2: In jpeg() : opening device failed

In the GUI version, a dialog appears saying: Unable to load

It seems that there should be an architecture folder (i386 or x64) after "libs", because that is where the dll is located.

Same thing happens with png(), tiff(), etc.
