Ada beberapa cara untuk menampilkan informasi CPU, yang pertama:

server# sysctl -a | egrep -i 'hw.machine|hw.model|hw.ncpu'

output

hw.machine: amd64
hw.model: Intel(R) Xeon(R) CPU           X3430  @ 2.40GHz
hw.ncpu: 4
hw.machine_arch: amd64

Mengambil informasi CPUINFO dari dmesg:

server# dmesg | grep -i cpu

atau

server# grep -i cpu /var/run/dmesg.boot

output

CPU: Intel(R) Xeon(R) CPU           X3430  @ 2.40GHz (2394.00-MHz K8-class CPU)
FreeBSD/SMP: Multiprocessor System Detected: 4 CPUs
cpu0 (BSP): APIC ID:  0
cpu1 (AP): APIC ID:  2
cpu2 (AP): APIC ID:  4
cpu3 (AP): APIC ID:  6
cpu0: <ACPI CPU> on acpi0
cpu1: <ACPI CPU> on acpi0
cpu2: <ACPI CPU> on acpi0
cpu3: <ACPI CPU> on acpi0
est0: <Enhanced SpeedStep Frequency Control> on cpu0
est: CPU supports Enhanced Speedstep, but is not recognized.

SMP: AP CPU #2 Launched!
SMP: AP CPU #1 Launched!
SMP: AP CPU #3 Launched!

Bisa juga dengan:

server# sysctl -a | grep -i cpu | less

License not correctly defined: multiple licenses in LICENSE, but LICENSE_COMB is set to single (or undefined)

Solusinya adalah menambahkan baris berikut pada /etc/make.conf.
Buat file tersebut bila belum ada.

LICENSE_COMB=multi

Problem selesai.

Konfigurasi diatas menyebabkan problem saat compile Libtool-2.2
Antisipasinya adalah memberikan remark (comment) pada konfigurasi yang ditambahkan diatas sebelum melakukan compile

Problem saat penambahan extension PHP:

Cannot find autoconf. Please check your autoconf installation and the $PHP_AUTOCONF environment variable is set correctly and then rerun this script.

server# export PHP_AUTOCONF="/usr/local/bin/autoconf"

Cannot find autoconf. Please check your autoconf installation and the $PHP_AUTOHEADER environment variable is set correctly and then rerun this script.

server# export PHP_AUTOHEADER="/usr/local/bin/autoheader"

Jalankan 2 perintah diatas saat mendapatkan masalah tersebut.
