On my Debian Squeeze 64-bit I also had to install the package "apache2-threaded-dev" with this command "apt-get install apache2-threaded-dev". Afterwards I did "pecl install apc" and everything seemed to work fine.
Installation
Diese » PECL-Extension ist nicht Teil von PHP.
Information zur Installation dieser PECL-Extension finden sie im Kapitel Installation von PECL-Extensions. Zusätzliche Informationen wie neue Releases, Downloads, Quelldateien, Maintainerinformation und ein CHANGELOG finden Sie hier: » http://pecl.php.net/package/apc.
Eine DLL-Datei für diese PECL-Erweiterung steht derzeit nicht zur Verfügung. Weitere Details finden Sie im Abschnitt zum Kompilieren für Windows.
Hinweis: Unter Windows benötigt APC ein existierenden temporären Pfad zu einem für den Webserver schreibbaren Verzeichnis. APC prüft die TMP, TEMP und USERPROFILE Environmentvariablen in dieser Reihenfolge und versucht schließlich das WINDOWS Verzeichnis zu nutzen, falls keine dieser Variablen gesetzt ist.
Hinweis: Für weiter in die Tiefe gehende technische Implementationsdetails nutzen Sie bitte die von den Entwicklern bereitgestellte » TECHNOTES Datei.
Pay attention to the fact that installing php-apc package gives you APC version 3.1.3p1, which is according to http://pecl.php.net/package/APC UNSTABLE. If you want the latest STABLE edition (3.1.9 by now), you should use 'sudo pecl install apc' instead.
When installing on Plesk and cPanel machines, I get the following error message:
[root@web1 ~]# pecl install apc

$PHP_AUTOCONF environment variable. Then, rerun this script.
ERROR: `phpize' failed
The problem is caused by the /tmp/ filesystem being mounted noexec, which keeps any programs on /tmp/ from being allowed to be executed, which breaks the install script.
To remount /tmp/ as executable, use:
[root@web1 ~]# mount -o remount,exec,suid /tmp
The it should install correctly.
After the install is done, remount the /tmp/ filesystem with the noexec permissions reset.
[root@web1 ~]# mount -o remount,noexec,nosuid /tmp
Installed successfully on different FreeBSD servers, with mmap and IPC semaphores, but I got an error on a 64 bits box :
apc_sem_create: semctl(65536,...) failed: Result too large
I had to increase maximum semaphore value :
# sysctl kern.ipc.semvmx=131068
kern.ipc.semvmx: 32767 -> 131068
# echo "kern.ipc.semvmx=131068" >> /etc/sysctl.conf
Works like a charm.
On Gentoo,
# emerge pecl-apc

Was enough for me. I use Ubuntu Server 8.10.
On Ubuntu I had to install the apache2-threaded-dev package. It's the the Etch repos.
debian etch installation
apt-get install apache2
apt-get install libapache2-mod-php5
apt-get install php-pear
apt-get install php5-dev
apt-get install make
apt-get install apache2-prefork-dev
pecl install apc
apache2-prefork-dev is necessary for not having the
"Sorry, I was not able to successfully run APXS."
error
