OSError: libparasail.so: cannot open shared object file: No such file or directory

Hi Jeff,

I encountered a problem when using pip install parasail:

docker run -ti ubuntu:trusty bash
apt-get update && apt-get install -y \
        git \
        python-dev \
        python-pip  \
        build-essential \
        liblzma-dev \
        libbz2-dev \
        zlib1g-dev
pip install parasail -vvv >log.txt
tail log.txt
    warning: no previously-included files matching '*.pyd' found anywhere in distribution

    writing list of installed files to '/tmp/pip-gdO3VT-record/install-record.txt'
Successfully installed parasail numpy

When trying to run the python script using parasail I get the following message:

/usr/local/lib/python2.7/dist-packages/parasail-1.0.2-py2.7.egg/parasail/libparasail.so

    self._handle = _dlopen(self._name, mode)
OSError: libparasail.so: cannot open shared object file: No such file or directory

I tried locating the so file:

find / -iname libparasail.so

But apparently there is none.

I attached the pip log: pip_parasail_log.txt

Don't know why it happens, on my Mac and another machine it worked without problems.

Compiling and installing parasail manually fixes the problem. However, it would be great to have pip handle this. Therefore, I would appreciate any help.

Thanks,
Philipp

This should be fixed in 55090dc. Should be part of the 1.1.6. release.
