Try using the entire path to the wget command.  Find the path to wget by using the locate OR whereis from the command line.  ( Example: locate wget or whereis wget )

Good luck

I ran into some errors so I will post some of the resolutions I found:

FreeBSD Apache HTTP Accept Filter Error

The resolution to the above problem is to a accf_http module, which function is to buffer incoming connections until a certain complete HTTP requests arrive, into FreeBSD kernel by using kernel linker:

kldload accf_http – This immediately activates this module

To always load enable HTTP Accept Filter FreeBSD kernel module (accf_http) during the boot, add the following line into /boot/defaults/loader.conf:

accf_http_load=”YES”
