don't print minimum version numbers when a tool fails to run. We already check

for version numbers before getting to this point and in the last year there
has not been a single case of this error being emitted and that being the
cause.  In fact, there's a bug about this error message being confusing.  So
just say an error occurred and point them for where to look (which is the
output of the tool that just failed).
