My recommendation would be to not use conda-forge at all for this build anymore. You may need to resolve https://issues.apache.org/jira/browse/ARROW-4868 > > 2.

I've brought this up in the past. This is the "nuke-it-from-orbit" approach that will address compatibility on many Linuxes. Uwe has done all the hard work to get things building on CentOS 5 with devtoolset-2 and you can ship these binaries on Ubuntu Trusty as well. > Any pointers on how to setup the environment in trusty? > > Krisitan - does any of the crossbow jobs build Gandiva on CentOs6 (or) > Trusty? We could then re-use the same for the Gandiva packaging work we do. > Per my comment above, consider a single devtoolset-2 build using the configuration used in https://github.com/apache/arrow/blob/master/python/manylinux1/Dockerfile-x86_64_base. We're already done all the work you need, including setting up the compiler toolchain and building all the dependencies in the Dockerfile. > Thanks a ton. > > Thx.
