If you get this, and think you used synaptic, you're confused.
Synaptic gets you prebuilt binaries from the repos it knows about.
What you show here is local compilation, possibly triggered by R. Not at all
the same.

Both r-cran-rgl and r-cran-xml exists _as pre-built binaries_. See above, do
not build them locally unless you have to AND know how to.

It works actually really well indeed, but it is still on Linux / Unix --
which is a whole new world onto itself for people just joining. As the joke
goes: "Unix is user-friendly, but it is picky about its friends."
Is there a local user group or a colleague you could bug locally?
