I'm not familiar with scons, but the output looks vaguely like that from an
autoconf-generated script.

If that's what it is, you'll probably need to look at config.log to find out
what's wrong; one way to debug this type of failure is to do something
analogous to:

./configure ... || (cat config.log; false)

in the build target, so that if configure fails, config.log is included in
the build log.

Depends on what the bug is.
