I couldn’t install the Mail PEAR package because the pear version shipped with the current CentOS/RHEL is 1.4.9, whereas the required version is 1.5.6 or above. The following is the error that you may see.
# pear install Mail WARNING: channel "pear.php.net" has updated its protocols, use "channel-update pear.php.net" to update Did not download optional dependencies: pear/Net_SMTP, use --alldeps to download automatically pear/Mail requires PEAR Installer (version >= 1.5.6), installed version is 1.4.9 pear/Mail can optionally use package "pear/Net_SMTP" (version >= 1.4.1) No valid packages found install failed
There are three problems above:
- WARNING: channel “pear.php.net” has updated its protocols, use “channel-update pear.php.net” to update
- Did not download optional dependencies: pear/Net_SMTP, use –alldeps to download automatically
- Main problem: pear/Mail requires PEAR Installer (version >= 1.5.6), installed version is 1.4.9
To fix problem #1 (update channel pear.php.net):
# pear channel-update pear.php.net Retrieving channel.xml from remote server Update of Channel "pear.php.net" succeeded
To fix problem #2 (Net_SMTP is not installed), run:
# pear install --alldeps Mail pear/Mail requires PEAR Installer (version >= 1.5.6), installed version is 1.4.9 downloading Net_SMTP-1.4.4.tgz ... Starting to download Net_SMTP-1.4.4.tgz (12,264 bytes) .....done: 12,264 bytes downloading Net_Socket-1.0.10.tgz ...

To fix problem #3 (old pear version), first upgrade pear:
# pear upgrade pear pear/PEAR dependency package "pear/Structures_Graph" downloaded version 1.0.4 is not the recommended version 1.0.3, but may be compatible, use --force to install pear/PEAR dependency package "pear/Console_Getopt" downloaded version 1.3.0 is not the recommended version 1.2.3, but may be compatible, use --force to install pear/Archive_Tar requires PEAR Installer (version >= 1.5.4), installed version is 1.4.9 pear/Console_Getopt requires PEAR Installer (version >= 1.9.1), installed version is 1.4.9 downloading Structures_Graph-1.0.4.tgz ... Starting to download Structures_Graph-1.0.4.tgz (30,318 bytes) .........done: 30,318 bytes downloading XML_Util-1.2.1.tgz ...

But this still doesn’t update base pear, so run:
# pear upgrade --force pear warning: pear/PEAR dependency package "pear/Console_Getopt" downloaded version 1.3.0 is not the recommended version 1.2.3 warning: pear/Archive_Tar requires PEAR Installer (version >= 1.5.4), installed version is 1.4.9 warning: pear/Console_Getopt requires PEAR Installer (version >= 1.9.1), installed version is 1.4.9 downloading PEAR-1.9.1.tgz ...

Now we can install pear’s Mail:
# pear install --alldeps Mail downloading Mail-1.2.0.tgz ... Starting to download Mail-1.2.0.tgz (23,214 bytes) ........done: 23,214 bytes install ok: channel://pear.php.net/Mail-1.2.0
You might also need Mail_mime:
# pear install Mail_mime downloading Mail_Mime-1.8.1.tgz ... Starting to download Mail_Mime-1.8.1.tgz (31,530 bytes) .........done: 31,530 bytes install ok: channel://pear.php.net/Mail_Mime-1.8.1
