TTSynth in F7.

[Darragh]

Hello all, 
I installed moonshine last night but cannot install ttsynthCore....rpm 
It is looking for a dependency like libsdc++ 

I'm ever so slightly stuck.  

I've tried looking for packages with that name or with a variation  of it
but have found nothing.  I've run yum with the speakupmodified repository
enabled and I've tried a few other minor things that don't spring to mind
this early in the morning.

Could someone please point me in the right direction?

Thanks
