mahotasbroken after upgrading ubuntu to 13.10

[jip]

Hello,
Since ubuntu was upgraded to 13.10. Importing mahotas previously build from
easy_install under ubuntu 13.04 failed.
I tried to rebuild mahotas (easy_install or from downloaded source) but
there is still an error:

directory).There are many reasons for this error the most common one is
that you haveeither not built the packages or have built (using `python
setup.py build`) orinstalled them (using `python setup.py install`) and
then proceeded to testmahotas **without changing the current
directory**.Try installing and then changing to another directory before
importing mahotas.*

Thanks

Hi,

I can guess that this means you have a semi-functional installation of
imread! If it was completely absent, then mahotas would detect this and
should work; if it was functional, then, well, it would work. But at
this semi-functional state, it screws up.

I think you can probably fix it by

sudo apt-get install libpng12-dev libtiff4-dev libwebp-dev

In my experience, Mahotas works best on Ubuntu 11.04 and Windows XP, Best
