Comment (by ryandesign@…):

 The first error in the log says:

 {{{
 :info:destroot
 /System/Library/Frameworks/Foundation.framework/Headers/NSObject.h:19:21:
 error: expected a type
 :info:destroot - (id)copyWithZone:(nullable NSZone *)zone;
 :info:destroot                     ^
 }}}

 This suggests to me that you are using a version of Xcode earlier than 7,
 which is not compatible with El Capitan. Upgrading Xcode is the first step
 in the [wiki:Migration migration instructions].
