Python, unable to install package, Mac OS X

Question

I'd like to install the following package for Python: http://www.daimi.au.dk/~mailund/suffix_tree/ I have downloaded the archive, unpacked it and run the following command in the terminal:

  python /Users/USRName/Documents/suffix_tree-2.1/setup.py install

When it is executed, the following error occures

  running install
  running build
  running build_py
  file suffix_tree.py (for module suffix_tree) not found
  file suffix_tree.py (for module suffix_tree) not found
  running build_ext

error: command 'gcc-4.2' failed with exit status 1

Would you be so kind to suggest me, how to fix it?

Answer 1

It seems clear from the error message that you are attempted to compile the file python-bindings.c, but that file doesn't exist in your current directory, probably because you are running the setup.py script from somewhere else.

So you should first cd /Users/USRName/Documents/suffix_tree-2.1/ then run python setup.py.
