And after fixing bitbake to get a build to start you get:
while building automake-native.Code:help2man: can't get `--help' info from automake-1.15 Try `--no-discard-stderr' if option outputs to stderr Makefile:3687: recipe for target 'doc/automake-1.15.1' failed
Which looks like an issue with a Perl script in the build, which I thought had been fixed. Clearly not...
