I know that - but I am not explicitly requesting it. In fact, I explicitly
put --without-valgrind, to no effect.
Here is what I have discovered may be the source of the problem. I had
inserted a enable_memchecker=yes line in my platform file. This apparently
has the unfortunate side effect of now requiring valgrind. IMHO, this should
not be setup that way per my earlier comment about requiring debuggers
unless memchecker has absolutely no other way to run - which looking at the
framework, would not appear to be true.
I then tried still using my platform file, but adding --disable-memchecker
to the configure line. The disable request was apparently ignored, at least
as far as the valgrind part of the request is concerned. The build failed at
the same point.
Removing the enable_memchecker=yes line from my platform file allows me to
successfully navigate configure.
So it appears to be a combination of memchecker=yes automatically requiring
valgrind, and the override on the configure line of a param set by a
platform file not working.
I can send you some stuff off-list in a little bit, if you still need it.
