The downloader need bz2 to extract the downloaded package. If bz2 is not available composer throws an exception witch is catched by the downloader and silently ignored. The Downloader just downloads every version and tries to extract it.

Hey Sascha!

Ideally, the Composer require section would allow platform specific requirements,
e.g. require > linux > ext-bz2 (to express that ext-bz2 is only required on linux),
but unfortunately that isn't supported by Composer.

Thank you for contributing, especially for digging into the source and finding a silent exception.

Merging.
