I'm trying to install psycopg2 into virtualenv using pip and getting the following error:

ld: library not found for -lssl
    clang: error: linker command failed with exit code 1 (use -v to see invocation)
    error: command 'cc' failed with exit status 1

Tried to google lssl library for python and can't find any mentions of this error. Am I doing something wrong?

pip 8.1.2
python 2.7.10
virtualenv 12.0.7
macos 10.12.1

Update: Actually looks like this question is a duplicate of this one: Can't install psycopg2 package through pip install... Is this because of Sierra? The solution from that question helped me. The issue was in missing xcode-cli tools and xcode-select --install fixed my problem.

So actually this question is a duplicate of this one: Can't install psycopg2 package through pip install... Is this because of Sierra?

In my case xcode-select --install fixed the problem. I suppose I got this issue because I updated my Xcode to the new version which was released yesterday.
