Seems like fedora's wine is missing ssl support: http://bugs.winehq.com/show_bug.cgi?id=8212 Guess buildRequires openssl-devel is all that is missing, since it autodetects ssl.h. Used here http://source.winehq.org/source/dlls/wininet/netconnection.c
Oh, not good +) I will push an upgrade asap. Thanks for reporting.
