GUB and mpfr/mpc

I'm trying to update GCC on GUB and have a new virtual machine with 
updated versions.  I was having problems getting MPFR to build, but it 
looks like I'ev fixed that with the new VM.  However, it looks to me like 
GCC 4.8.2 has a new dependency on MPC that older versions did not: there 
appears no mention of MPC as a package in the current version of GUB.  My 
most recent failure says this:

checking for the correct version of gmp.h... buggy but acceptable
checking for the correct version of mpfr.h... yes
checking for the correct version of mpc.h... no
configure: error: Building GCC requires GMP 4.2+, MPFR 2.4.0+ and MPC 

So it looks like we need to add a dependency on MPC.  Problem is, I don't 
have a clue how to do this.  I could try some stuff, but can anyone here 
help with how this dependency should be added to GUB?
