minor inconvenience bug in PEAR Installer may affect upgrade to 1.5.0

Bertrand Gugger recently discovered some odd behavior. He tried to upgrade to PEAR from version 1.4.11, and encountered: |pear/PEAR dependency package "pear/Console_Getopt" downloaded version 1.2.2 is not the recommended version 1.2.1, but may be compatible, use --force to install downloading Archive_Tar-1.3.2.tgz ... Starting to download Archive_Tar-1.3.2.tgz (17,150 bytes) ......done: 17,150 bytes downloading Structures_Graph-1.0.2.tgz ... Starting to download Structures_Graph-1.0.2.tgz (30,947 bytes) ...done: 30,947 bytes downloading Console_Getopt-1.2.2.tgz ... Starting to download Console_Getopt-1.2.2.tgz (4,252 bytes) ...done: 4,252 bytes upgrade ok: channel://pear.php.net/Console_Getopt-1.2.2 upgrade ok: channel://pear.php.net/Structures_Graph-1.0.2 upgrade ok: channel://pear.php.net/Archive_Tar-1.3.2 | In other words, it upgraded all of the dependencies, but not PEAR itself. Trying again, he got: |pear upgrade pear downloading PEAR-1.5.0.tgz ... Starting to download PEAR-1.5.0.tgz (286,143 bytes) ...........................................................done: 286,143 bytes upgrade ok: channel://pear.php.net/PEAR-1.5.0 PEAR: Optional feature webinstaller available (PEAR's web-based installer) PEAR: Optional feature gtkinstaller available (PEAR's PHP-GTK-based installer) PEAR: Optional feature gtk2installer available (PEAR's PHP-GTK2-based installer)To install use "pear install pear/PEAR#featurename" In other words, it worked. Very curious behavior. Fortunately, it is completely harmless. This bug: | http://pear.php.net/bugs/bug.php?id=10130 documents the problem. If you are anyone you know encounters this issue, let them know that it is a minor inconvenience that will be fixed for all future versions in PEAR 1.5.1, coming soon. Sorry about that, Greg
