consider adding "install the python-dev package" step to quickstart

[daira]

When building Tahoe-LAFS on Unix-like platforms without the python-dev package installed, the error is typically:

fatal error: Python.h: No such file or directory

I know zooko wants to minimize the complexity of the quickstart instructions, but since this error can be fixed in many cases by running "sudo apt-get install python-dev" (or equivalent for other package managers), we might consider mentioning that in quickstart.

note this might be "python-devel" on redhat-derived systems (including Fedora)

[zooko]

My objection to this is that it is platform-specific, i.e. it will make Windows users think that the quickstart doesn't apply to them. On the other hand, people keep telling me that the whole idea of a platform-portable quickstart is impossible and/or not needed, so maybe instead of adding "python-dev" to the quickstart we should rm the quickstart and redirect all links that used to go to the quickstart to ​https://tahoe-lafs.org/trac/tahoe-lafs/wiki/Installation ?

Removing quickstart would be out-of-scope for 1.10.2. Adding a note about python-dev or python-devel would not be. I think that an explicit "This is not needed on Windows." would be sufficient to avoid the impression that quickstart doesn't apply to Windows users.

Bleh, I give it -0. Also remember that python-dev/python-devel is not needed if the C-containing deps are already installed or if binary eggs of them are available.

(-0 means go ahead, and just endure my angry stares stabbing into your back as you do it.)
