Bug 588984 – cryptography-1.1.2 won't compile due to redeclarations

• Product: Gentoo Linux
• Status: RESOLVED DUPLICATE

[Description Paul McDermott 2016-07-17 10:50:09 UTC]

I currently have dev-python/cryptography-1.1.2 installed. But a @world update is forcing it to be recompiled, which is failing due to redefinitions of declarations from /usr/include/opensll/ssl.h which appears to be from dev-libs/openssl-1.0.2h-r2.
