port lang/gcc45 - not sure how to interpret GCC developers' advice

On sparc64 -current r212302 I'm having trouble
building port lang/gcc45.

Before I go any further, let me just check if anybody
on this list has built gcc45 successfully?

Here's my GCC bug submission:

I just can't understand what the GCC folks tell me to do.

They referred me to this page:

and apparently to this paragraph:

Newer versions of the GNU Multiple Precision Library (GMP),
the MPFR library and the MPC library are known to be
miscompiled by earlier versions of GCC on these platforms.
We therefore recommend the use of the exact versions of
these libraries listed as minimal versions in the prerequisites. 
*end quote*

The prerequisites link lists:

GNU Multiple Precision Library (GMP) version 4.3.2 (or later)
MPFR Library version 2.4.2 (or later)

I've installed:


So do they mean to say that I should downgrade to GMP 4.3.2 and
MPFR 2.4.2?

Or do they want me to compile these libraries with say gcc44,
instead of the system 4.2.1?

many thanks
