python-mcrypt is a Python interface to the mcrypt library. You have to install mcrypt first.

found the solution for this issue .
For mcrypt.h, libmcrypt-dev needs to install by following command
sudo apt-get install libmcrypt-dev
after installing with above command python-crypt got install successfully with below command
pip install http://labix.org/download/python-mcrypt/python-mcrypt-1.1.tar.gz

Installing aspell for python 3 on MacOS X

I am trying to install aspell for Python 3 (on MacOS X 10.11), and have encountered an issue (the same one) using both pip and the manual installer (by cloning the git repo). I have already installed aspell using MacPorts (sudo port install aspell) as well as the english dictionary (sudo port install aspell-dict-en).
The error is obvious (aspell.h cannot be found), however I have no idea how to fix it.
Any help would be greatly appreciated.

Asked the same question on the project's GitHub page. Original can be found here. Copied here for convenience.
In case anybody encounters the same issue, I had installed aspell using MacPorts (sudo port install aspell) and had to include the dir '/opt/local/include', which is where the header file for aspell (aspell.h) was located.
Hence, my setup.3.py looks like this:
module = Extension('aspell',
libraries = ['aspell'],
library_dirs = ['/usr/local/lib/'],
include_dirs = ['/opt/local/include'],
sources = ['aspell.c']
)

Error installing Pygame on Ubuntu

So I've been following some instructions on how to install Pygame from this link here :http://programarcadegames.com/index.php?showpart=0#section_0.3
The the final three commands are as follows
$
# Use mercurial to clone current code
hg clone https://bitbucket.org/pygame/pygame
# Build and install
cd pygame
sudo python3 setup.py
$
When I run the final command to run the setup file, I get this error after everything before it runs fine.

Any ideas as to how I cann fix this issue and complete my Pygame installation?

You need to install the python development package, which includes those header files.
sudo apt-get install python-dev

Cython Install GCC error

Trying to install Cython on a small VPS running Ubuntu Server. Did
sudo apt-get install gcc
and then
python setup.py install
In the Cython directory, but I get this peculiar error.

Why should I need a 'development version of Python'? Running Python 2.6.5 (r265:79063, Apr 16 2010, 13:57:41). Thanks!

You need the developer version of Python - i.e. the Python header files (Python.h)
sudo apt-get install python-dev

You need the headers included in the development version of Python, i.e. python.h. It should be packaged in Ubuntu as python-dev.
