If the system wgetrc has the
content-disposition = onoption, the file is actually saved asPHP-Parser-5.0.0.tar.gz, causing a subsequent failure.Even with
content-disposition = off, if for any reason the download file already exists and is corrupted, it won't be overwritten, and a new file such asv5.0.0.tar.gz.1is saved instead.We solve both problems by enforcing the name of the downloaded file.
Also, if for any other reason the unpacking should fail, remove the created directory to allow further attempts.
