Pip install does not use symlinks for bufrtables if wheels are enabled

Running

pip install pybufr-ecmwf does not use symlinks for the BUFR tables.

This leads to 1.5 GB of used space for each environment in which it is installed in this way.

This is not really critical for me since I use my conda package but it might be interesting to know for others.

that's strange. I just did a test on my own linux machine, and there I do not see this symlink problem. The installed module in $HOME/.local/lib/python2.7/site-packages/pybufr_ecmwf/ is just 18MB in size. Could you give me some details on your machine and software/OS versions?

I've investigated a little bit and the reason for it is bdist_wheel which seems to be the default now. I'm using pip 8.1.1 and normal installation without the symlink problem can be achieved by disabling the building of wheels with the --no-binary flag

OK, thanks for your investigations. I am thinking of getting rid of these symlinks completely in a next version, but this will require some recoding. It may take a while before this is implemented.
