Can't install Caravel on OSX 10.11.3

[veenits]

I'm trying to install caravel by doing a pip install caravel. I get the below error -

Looks like you paste the "cleaning up" part of the log. Cleaning up happens after the error occurs.

My bad. I did a re-run. Here is what I got -

@mistercrunch Any thoughts?

[andrewhn]

try brew install libffi and re-install

From https://github.com/blockstack/blockstack-profiles-py/blob/master/troubleshooting.md

[veenits]

I did a brew install libffi. Here is the output -

==> Downloading https://homebrew.bintray.com/bottles/libffi-3.0.13.el_capitan.bottle.tar.gz
######################################################################## 100.0%
==> Pouring libffi-3.0.13.el_capitan.bottle.tar.gz
==> Caveats
This formula is keg-only, which means it was not symlinked into /usr/local.

Some formulae require a newer version of libffi.

Generally there are no consequences of this for you. If you build your
own software and it requires this formula, you'll need to add to your
build variables:

    LDFLAGS:  -L/usr/local/opt/libffi/lib

==> Summary
🍺  /usr/local/Cellar/libffi/3.0.13: 15 files, 374.6K

Assuming that it's successfully installed, I still get this after the command pip install caravel

Am I supposed to change any build variables before re-installing caravel?

[veenits]

I just got it to working. Here is what I did -

brew install pkg-config libffi openssl python
env LDFLAGS="-L$(brew --prefix openssl)/lib" CFLAGS="-I$(brew --prefix openssl)/include" pip install cryptography

The pip install cryptography did not work. But, I did a conda install cryptography instead and got it set up.

After that, it was just pip install caravel
