I recently installed PHP 4.3.11 from source (due to configuration requirements) on to an OpenBSD i386 v3.7 server. The installation went perfectly as it has many times before, however I found out that the PEAR script was not installed (normally in /usr/local/bin). I discovered this when trying to install some pear packages doing “pear install packagename”. I get a returned error of “-bash: pear: command not found”. I tried locating the PEAR script using “find / -name pear” and “/usr/libexec/locate.updatedb” then “locate -i pear”. The result came up empty with no PEAR script in the returned results. I double checked the PEAR documents, PHP documents and ./configure all three places stated PEAR is installed by default unless a parameter is provided at configure with –without-pear. I’m still not aware as to why the PEAR script was not installed however with help by …
