Fix Pear/Mail due to CentOS/RHEL repos using old pear

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:

  1. WARNING: channel “pear.php.net” has updated its protocols, use “channel-update pear.php.net” to update
  2. Did not download optional dependencies: pear/Net_SMTP, use –alldeps to download automatically
  3. 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

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 ...

...done: 17,729 bytes
upgrade ok: channel://pear.php.net/XML_Util-1.2.1
upgrade ok: channel://pear.php.net/Structures_Graph-1.0.4

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

To install use "pear install pear/PEAR#featurename"

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
