the MD5 checksum in package.xml for a file only works with the PEAR installer when provided in lowercase. If capital letters (A-F) are used, a "bad checksum" warning is returned.

Reason: md5_file() seems to return MD5 checksums in lowercase, however some MD5 calculation tools (e.g. the command line tool at return checksums in upper case.
The "error" (if you can call it that way) is in line 276 of PEAR\Installer.php:

if ($md5sum == $atts['md5sum']) {

The following would eliminate the problem:

if ($md5sum == strtolower($atts['md5sum'])) {
