How install django-auth-ldap==1.2.7 in Heroku servers?

Question

I'm trying to install this lib django-auth-ldap==1.2.7 using pip install in requirements.txt.

I'm using Heroku services to deploy.

However, every time I try to push/deploy the code I can't quite finish the dependency check/install because pops this error:

remote:        Modules/LDAPObject.c:18:18: fatal error: sasl.h: No such file or
directory

I fallowed this question and answers: python-ldap failed to install in Heroku

But with no luck.

Basically, I've tried to use a third party BUILDPACK:

heroku config:set BUILDPACK_URL=https://github.com/damgad/heroku-buildpack-python-ldap.git

And

heroku buildpacks:set https://github.com/damgad/heroku-buildpack-python-ldap.git

But still not working.

Can someone please,

1. Help me showing me a way to build my own BUILDPACK or
2. Pointing me an alternative solution?

Thanks!

---EDIT----

Just found out that a few good people are working to make it work.

There is a pull request trying to solve this problem of mine directly in heroku default buildpack.

https://github.com/heroku/heroku-buildpack-python/pull/271

I will keep this question open and updated in case someone wonder the same.

Thanks!

That's not how you use a custom buildpack; all you've done is set an environment variable called BUILDPACK_URL.

Instead, follow the documentation: you need heroku buildpacks:set https://......
