The latter of the two you mention: powerpc-e500v2-linux-gnuspe

(On Fedora 14 x86-64, although I don't think it matters quite so much
for this issue, other than the "static libs are a separate package"

Unfortunately, I don't know.  It seems that *something* on the host
side wants libstdc++ for static linking; exactly what, I don't recall.
 (I suppose I can erase that package and recompile, to see what

Interesting; looks like the static lib is a part of -devel for F13
(and, presumably, earlier), but not on F14.

Anyway.  Running the experiment now.  Will try to update this thread
as I find out what breaks.  :)

Perhaps.  Again, I have to make apologies for the fact that I can only
make patches for items which are show-stoppers for me; I hope that
they're useful to others, but unfortunately I'm not in a position to
do exhaustive fixing.  :(

Thanks for all the work you've been adding to ct-ng lately!
