MLPy depends on GNU Scientific Library (GSL), which you need to install first.
You can install it either with brew install gsl or manually from source.
For manual installation, instructions can be found here. The relevant steps are as follows:
- go to: http://www.gnu.org/prep/ftp.html
- click on an ftp link close to your location
- find the gsl/ directory and click on it
- find the gsl-VERSION.tar.gz file, where version is 1.14 or greater. Click on that file to download it.
- In a terminal window extract the tar.gz file using tar -xzf gsl-VERSION.tar.gz and then cd to the ./gsl-VERSION directory
- Look at the INSTALL file. It will probably tell you to run ./configure, then make, and then make install (and you might have to login as the superuser (sudo)

I am actually getting the same issue today while installing mlpy. Based on the mlpy documentation. Here is the method to solve this issue.
According to the installation section in the mlpy documentation:
If the GSL header files or shared library are in non-standard locations on your system, use the --include-dirs and --rpath options to build_ext:
$ python setup.py build_ext --include-dirs=/path/to/header --rpath=/path/to/lib
$ python setup.py install
We have to assign the header and lib. Based on How to obtain and install GSL,
Under Search Paths/Header Search Paths type /opt/local/include
Under Search Paths/Library Search Paths type /opt/local/lib
The quick answer is running the below command:
sudo python setup.py build_ext --include-dirs=/opt/local/include --rpath=/opt/local/lib
sudo python setup.py install
Hope this will be helpful.
