DistributionNotFound: PythonRequirement() on Raspberry Pi (armhf)
I try to build our application on Raspberry PI (http://www.raspberrypi.org/) with python pants. Actually I'm doing this in raspbian run in qemu (http://xecdesign.com/qemu-emulating-raspberry-pi-the-easy-way/) - this is the easiest way to reproduce it without having a raspberry pi hardware.
(deploy)pi@raspberrypi ~/wh-monit/src $ pants --version

(deploy)pi@raspberrypi ~/wh-monit/src $ pip search twitter.pants

Usage:
pants build (options) [spec] (build args)
pants build (options) [spec]... -- (build args)
Options:
--version show program's version number and exit
-h, --help show this help message and exit
--no-pantsrc Specifies that pantsrc files should be ignored.
--log-exit Log an exit message on success or failure.
-t CONN_TIMEOUT, --timeout=CONN_TIMEOUT
Number of seconds to wait for http connections.
-i INTERPRETER, --interpreter=INTERPRETER
The interpreter requirement for this chroot.
-v, --verbose Show verbose output.
Builds the specified python target(s).
It's not about pyyaml, when I remove this dependency it would fail on voluptuous, then furl etc. Installing those packets via pip works perfectly:

I know that I can build locally eggs and then pass them to pants, but it's very inconvenient.
out of curiosity, when you do ./pants py -v, does it list more than one interpreter? it's possible you have a good interpreter and a bad interpreter (when it comes to correctly building C extensions) and pants is picking the bad one.
Looks like I have four interpreters:

As I'm using virtualenv, it should use the one from virtualenv:
(deploy)pi@raspberrypi ~/wh-monit/src $ python --version
Python 2.7.3
(deploy)pi@raspberrypi ~/wh-monit/src $
I tried to tell pants which interpreter to use, but I failed:

Then I found a "-v" flag, and used it :)

So I believe pants use proper interpreter (the one from virtualenv), so probably it's not the case.
Do you have any other clues that would help to trace this issue?
