I've had a reply from 1 person that the "std.ihx" file -does- allow
the Intel-Mac to work properly with the USRP<->USB<->GR transports.
So I have kept experimenting, and come up with more statistics, but
maybe not any better knowledge of the underlying issue. Basically,
most statistics point to problems with XCode 2.4 for Intel-Mac; yet
some folks don't have functionality using XCode 2.2.1 or 2.3, so
that's not everything.
In the mean time, if you have an Intel-Mac and want to use GNU Radio,
you can download a -known working- pre-compiled version of SDCC
(2.4.0) for Intel-Mac's from my GNU Radio WWW area (it's about 1.88 MB).

Here are the added "statistics":
* I can recompile SDCC 2.4.0 (via DarwinPorts, with no updates for
along time so it things SDCC 2.4.0 is current) on the -previously
working- MacBook Pro (MBP) using XCode 2.4, and it no longer works.
This is "good" since it confirms that XCode is an issue as I've been
suspecting.
* The "std.ihx" file can be moved from a PPC Mac or elsewhere, since
it represents code to be uploaded to the FPGA (I assume). Hence the
easiest way to get things going on the Intel-Mac is to do a current
SVN checkout on both that computer and some other non-Intel-Mac
computer, then compile and install both, then move the file
"{gr_prefix}/share/usrp/rev2/std.ihx" from the non-Intel-Mac to the
Intel-Mac.
* I can make a tarball of (already working on the MBP) SDCC 2.4.0,
move it to the 20" iMac, untar and install it (into /opt/local ...
careful), and that install now works.
* I can compile SDCC on the iMac using XCode 2.3 and it won't create
a "good" std.ihx file. This again points to XCode not compiling SDCC
correctly, since clearly SDCC is functional and the original code is
the same.
