BUG:The old module_version() uses import() which fails for packages where the pip package name differs from the Python module name (e.g., flagtree installs as 'triton' module).

FlagTree is installed, but FlagTree-related information is not detected; instead, Triton-related information is detected. This is because the pip package name of FlagTree is flagtree, while its import package name is triton.
