There's compilation error during kdepim-4.7.4 compilation:
[ 35%] Building CXX object messagecomposer/CMakeFiles/messagecomposer.dir/akonadisender.o
/usr/src/packages/kde4/4.7.4/kdepim-4.7.4/messagecomposer/akonadisender.cpp: In member function 'void AkonadiSender::sendOrQueueMessage(const boost::shared_ptr<KMime::Message>&, MessageSender::SendMethod)':     
/usr/src/packages/kde4/4.7.4/kdepim-4.7.4/messagecomposer/akonadisender.cpp:138: error: reference to 'Message' is ambiguous
/usr/src/packages/kde4/4.7.4/kdepim-4.7.4/messagecomposer/util.h:35: error: candidates are: namespace Message { }
/usr/include/kmime/kmime_message.h:82: error:                 class KMime::Message
make[2]: *** [messagecomposer/CMakeFiles/messagecomposer.dir/akonadisender.o] Error 1
make[1]: *** [messagecomposer/CMakeFiles/messagecomposer.dir/all] Error 2

I believe an error says itself, small ambiguous call:
if ( !Message::Util::sendMailDispatcherIsOnline() )

Making an explicit reference to global namespace is enough to fix it:
if ( !::Message::Util::sendMailDispatcherIsOnline() )

But I think it's better to sort out this name collision.

Reproducible: Didn't try

Steps to Reproduce:
1. Start the compilation of kdepim-4.7.4.
2. Notice some strange behavior during compilation.

Actual Results:  
The package fails to compile.

Expected Results:  
The package compiles successfully.
