The current version of PHPUnit is 3.6, but until I update my code I need to use 3.5.15 instead. I'm having a lot of trouble trying to get 3.5.15 installed.
I start with a clean install of Zend Server, which only has a few basic PEAR packages installed. I channel-discover pear.phpunit.de and pear.symfony-project.com. Then I try installing 3.5.15 from a URL, but it fails:
# pear install http://pear.phpunit.de/get/PHPUnit-3.5.15.tgz
downloading PHPUnit-3.5.15.tgz ...
Duplicate package channel://pear.phpunit.de/PHPUnit-3.5.15 found
Duplicate package channel://pear.phpunit.de/PHPUnit-3.6.0 found
install failed
Next, I try installing from a downloaded file, but that also fails:
# pear install ~/Desktop/PHPUnit-3.5.15.tgz
Duplicate package channel://pear.phpunit.de/PHPUnit-3.5.15 found
Duplicate package channel://pear.phpunit.de/PHPUnit-3.6.0 found
install failed
And then from PEAR directly ... which installs 3.6 instead of what I asked for!
# pear install phpunit/PHPUnit-3.5.15
phpunit/PHPUnit can optionally use package "pear/XML_RPC2"
phpunit/PHPUnit can optionally use PHP extension "dbus"
phpunit/DbUnit requires package "phpunit/PHPUnit" (version >= 3.6.0), downloaded version is 3.5.15
phpunit/PHPUnit requires package "phpunit/DbUnit" (version >= 1.0.0)
phpunit/PHPUnit can optionally use package "phpunit/PHP_Invoker" (version >= 1.0.0)

Even using the -f option, to try to force an installation of the version I asked for, doesn't change anything.
How do I get 3.5.15 installed?
PHPUnit-3.5.15 requires DbUnit, but the latest version of DbUnit (1.1.0) requires PHPUnit-3.6. So that's why, when I installed PHPUnit 3.5.15, 3.6 would be installed instead. I worked around the problem by specifically installing DbUnit-1.0.3.
I'll accept my own answer, but it's not a complete answer - an attempt to install PHPUnit 3.5 results in the installation of a module which then forces the install of PHPUnit 3.6, and that doesn't seem right. This looks like a packaging problem, but I couldn't figure out where to report it.
