Python pip can't seem to find Python.h despite python-dev installed - python-2.7

Question

I am currently trying to install getch, a simple python package and have run into quite a bit of difficulty. I recently installed pypy in a kind of messy way (I wanted to get numpy with pypy working, which was a considerable pain) so that might have to do with the problem I'm having.
Okay, so I try to run
sudo pip install getch
and I get the error...
error: command 'x86_64-linux-gnu-gcc' failed with exit status 1
and as a bonus, a character encoding error.
This is the error that folks get when they don't have python-dev installed. However, I do. I attempted to work around this issue, by downloading the package and installing it manually.
sudo python setup.py install
also gave me the gcc error from above. I have gcc installed, and x86_64-linux-gnu-gcc works in terminal fine. I made a simple hello world program in c that simply includes Python.h. That worked fine as well. After remove --purging pypy, python, and python-dev from my system, I re-installed just python and python-dev and I still have the same silly issue.
Anyone have any thoughts?
Here's a pastebin of the exact error I'm getting. pastebin.com/mjRdADZx

You need to manually download the Python 2 version and install it. The version downloaded by pip is for Python 3.
The clue is this line:
Downloading/unpacking getch
Downloading getch-1.0.tar.gz # This is the Python 3 package
Running setup.py egg_info for package getch
Installing collected packages: getch
Running setup.py install for getch
building 'getch' extension
gcc -pthread -fno-strict-aliasing -DNDEBUG -g -fwrapv -O2 -Wall -Wstrict-prototypes -fPIC -I/usr/local/include -I/usr/include -I/usr/include/python2.7 -c getchmodule.c -o build/temp.linux-i686-2.7/getchmodule.o
getchmodule.c: In function ‘getch_getche’:
getchmodule.c:36:6: warning: unused variable ‘ok’ [-Wunused-variable]
getchmodule.c: In function ‘getch_getch’:
getchmodule.c:43:6: warning: unused variable ‘ok’ [-Wunused-variable]
getchmodule.c: At top level:
getchmodule.c:54:15: error: variable ‘getchmodule’ has initializer but incomplete type
getchmodule.c:55:4: error: ‘PyModuleDef_HEAD_INIT’ undeclared here (not in a function)
The Python 2 version is also 1.0, but the file name is getch-1.0-python2.tar.gz. You can download it directly from the index.
Once downloaded, extract the archive and then python setup.py install from within the extracted directory.
