[gentoo-user] Help working around a bug...

Hi
I am a relative newbee to GenToo (*though familiar with all sorts of 
Unix/Linux/BSD OS)
I am currently unable to complete a sync / build @world cycle because of a
bug building enchant-2.2.8 , compile fails because it doesn't recognize the
ObjC "@" syntax.  There is a bug filed :
https://bugs.gentoo.org/show_bug.cgi?id=718634
that has a suggested fix that looks appropriate:

./configure --without-applespell --without-aspell --enable-relocatable

(Not sure about the --without-aspell bit, and I think this bug may have 
some relation to
using GNUstep bits)

How do I override the ./configure options for emerge  [-r] ?

Chris
