Ben, a quick look at installing_faq.rst shows some anachronisms:
references to installing obsolete versions.  This is another worm
barrel.  Those anachronisms are not the only problems with the
file--or
with installation in general.

Eric


I'll double-check for that.  Note that I am merely moving my changes 
over to INSTALL, so whatever INSTALL has should be the final version.  
Below is the current diff between them.


On a separate note, I think there might be some unspecified 
requirements for building the documentation.  On my newly set up 
Ubuntu machine, the build gets to the thumbnails stage and recognizes 
that I have no thumbnails, and then the process goes to sleep.  Maybe 
we have an error check missing somewhere?
Generating the thumbnails has no additional requirements (it uses 
matplotlib's image module to scale the images).  However, it may be a 
problem with multiprocessing -- the thumbnails are generated in parallel 
on multi-core machines.  I haven't had problems myself, but it seems 
multiprocessing doesn't always work in certain environments.


Can you do me a favor?  Can you edit gen_gallery.py and replace the line 
beginning with "pool.map" to just "map" and let me know if that resolves 
this issue?  If it does, perhaps we should not use multiprocessing here.

Given this seems to be one of the longer stages of the build process,
I'd appreciate if if we identified and fixed the underlying problem and
not simply sweep it under the rug.

Don't have a lot of time because I am on travel right now, but I think I
figured out the cause.  For whatever reason, there was some sort of missing
file error that caused the generation of the thumbnails to drop down to the
debugger prompt.  When within the multiprocessing pool, everything just
pauses, but nothing shows because the input is disconnected.  After a call
to clean, I was able to run the docs with and without "pool".

I hope that is a useful tip that could help figure out how to prevent a
unresponsive process.
