Python fails to install on MacOS 10.8

[avaranovich]

Hi,

Here is some interesting stuff from the output of brew install -v python

Python build finished, but the necessary bits to build these modules were not found:
_bsddb
dl
imageop
linuxaudiodev
ossaudiodev
spwd
sunaudiodev

To find the necessary bits, look in setup.py in detect_modules() for the module's name.

Failed to build these modules:
_elementtree
_multiprocessing
_sqlite3
pyexpat
...

And finally

Any ideas what's going wrong?

Brew doctor seems not heavily complaining:

Error: Some directories in /usr/local/share/man aren't writable.
This can happen if you "sudo make install" software that isn't managed
by Homebrew. If a brew tries to add locale information to one of these
directories, then the install will fail during the link step.
You should probably chown them:

/usr/local/share/man/de
/usr/local/share/man/de/man1

Error: "config" scripts exist outside your system or Homebrew directories.
./configure scripts often look for *-config scripts to determine if
software packages are installed, and what additional flags to use when
compiling and linking.

Having additional scripts in your path can confuse software installed via
Homebrew if the config script overrides a system or Homebrew provided
script of the same name. We found the following "config" scripts:

/Library/Frameworks/Python.framework/Versions/2.7/bin/python-config
/Library/Frameworks/Python.framework/Versions/2.7/bin/python2-config
/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7-config

Error: /usr/X11 is a symlink
Homebrew's X11 support has only be tested with Apple's X11.
In particular, "XQuartz" and "XDarwin" are not known to be compatible.

Until #13037 lands, it's hard to diagnose.

[samueljohn]

At a first look, I think the config scripts found may perhaps be the cause. When the system python is mixed with the homebrew build thing will break. This is especially the case for SQLite bindings.

Show us your brew --config and please put such long outputs into a gist.github.com and link it here.

[samueljohn]

Perhaps #12968 helps with (some?) of your problems here?

You could try to cd /usr/local, git checkout -b test and brew pull 12968 to check it.
Revert back via git checkout master

[avaranovich]

Here is a brew --config output https://gist.github.com/3003312

[avaranovich]

I tried #12968 and it worked for me!

[samueljohn]

Thanks @avaranovich. Now I hope #12968 gets pulled soon.

[rors]

I also just tried #12968 as per the comment above, and it worked for me. Let's hope that gets pulled soon! Thanks.

[samueljohn]

@rors Thanks for your test! I just have to integrate the latest code-review. Then I'll ask one of the core-members to pull the trigger :-)

[jalama]

just to pile on #12968 worked for me also
