htop(1) requires linprocfs(5) to be mounted. If you don't
have it mounted already, please add this line to /etc/fstab
and run `mkdir -p /usr/compat/linux/proc; ln -s /usr/compat /compat; mount linproc`:
linproc /compat/linux/proc linprocfs rw,late 0 0
***********************************************************
*** [pre-configure] Error code 1

Stop in /usr/ports/sysutils/htop.
*** [install] Error code 1

Stop in /usr/ports/sysutils/htop.

修改/etc/fstab，並建立以下目錄即可

# vi /etc/fstab
linproc /compat/linux/proc linprocfs rw,late 0 0

# mkdir -p /usr/compat/linux/proc ; ln -s /usr/compat /compat ; mount linproc

# make install
