I'm attempting to install a custom build on heroku, so I'm using a variety of ways to attempt a third part installing using the buildpacks. In my .buildpacks file I have:
https://github.com/ddollar/heroku-buildpack-apt
https://github.com/heroku/heroku-buildpack-python.git
and in my Aptfile I have the following: libgeoip-dev which is a pre-requisite for geoip which is installed with the requirements.txt (GeoIP==1.3.2)
Here are my environment variables:
remote: C_INCLUDE_PATH is /app/.heroku/vendor/include:/app/.heroku/vendor/include:/app/.heroku/python/include
remote: CPATH is /tmp/build_xxxxx/.apt/usr/include:
remote: LD_LIBRARY_PATH is /app/.heroku/vendor/lib:/app/.heroku/vendor/lib:/app/.heroku/python/lib
The error message I am getting is:
remote: building 'GeoIP' extension
remote: creating build
remote: creating build/temp.linux-x86_64-2.7
remote: gcc -pthread -fno-strict-aliasing -g -O2 -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -fPIC -I/app/.heroku/python/include/python2.7 -c py_GeoIP.c -o build/temp.linux-x86_64-2.7/py_GeoIP.o -fno-strict-aliasing
remote: creating build/lib.linux-x86_64-2.7
remote: gcc -pthread -shared build/temp.linux-x86_64-2.7/py_GeoIP.o -lGeoIP -o build/lib.linux-x86_64-2.7/GeoIP.so
remote: /usr/bin/ld: cannot find -lGeoIP
remote: collect2: error: ld returned 1 exit status
remote: error: command 'gcc' failed with exit status 1
What is the smartest way to fix this? I.e. I guess I cannot change where the package manager installs. Is there a way around this?

The heroku-buildpack-python buildpack is not playing nice with heroku-buildpack-apt buildpack as it is clobbering important variables for gcc to link your python extension with the geoip lib. File a bug on the issue tracker.
