[gpaw-users] GPAW installation through Homebrew on Mac OS X Mavericks

[Varadharajan Srinivasan]

Dear Ask,

Upon googling I had found some links pointing to similar errors. See for
instance,
http://stackoverflow.com/questions/16748994/python-ssl-connection-eof-occurred-in-violation-of-protocol

Apparently there is some incompatibility between SSL and the version of TLS
used. I actually don't understand it completely so I couldn't try the
suggested fix. Do you think this could be the issue?

Vardha.
