Thanks you for your reply. Drupal is a Web Content Management System. 
Drush is an ancillary project that automates numerous common
maintenance tasks involving a Drupal installation.  Both Drupal and
Drush are written in PHP.  Drupal was installed using 'pkg install
drupal7'

The jail does have internet access via NAT configured on our gateway
router.  Installing and updating packages from within the jail work
fine.  I can ssh in and out.  I can ping the jail.  I cannot ping out,
but that is expected behaviour for a jail.

I regret is my original question was perfunctory. The issue seems to
me to be one of a missing component or php module rather than anything
to do with network connectivity.

I initially took a too literal approach to installing Drush as there
exists a package for it.  I installed Drush within the jail via pkg
install and things work fine.

I am not sure what the issue is with php because I can wget the file
from inside the jail, I just cannot get the recommended php command to
work.

I ran across references to 'extension=php_openssl.dll' in php.ini
having some bearing on this elsewhere 
(https://stackoverflow.com/questions/5444249/unable-to-find-the-wrapper-https-did-you-forget-to-enable-it-when-you-config)
but I cannot see that a .dll and FreeBSD have much in common. 
None-the-less I checked this and found these references:

# grep php_openssl /usr/local/etc/*
/usr/local/etc/php.ini:;extension=php_openssl.dll
/usr/local/etc/php.ini-development:;extension=php_openssl.dll
/usr/local/etc/php.ini-production:;extension=php_openssl.dll

Changing the commented reference in /usr/local/etc/php.ini gives the
dismal results I anticipated:

# php -r
"readfile('https://s3.amazonaws.com/files.drush.org/drush.phar');" >
drush
PHP Warning:  PHP Startup: Unable to load dynamic library
'/usr/local/lib/php/20131226/php_openssl.dll' - Cannot open
"/usr/local/lib/php/20131226/php_openssl.dll" in Unknown on line 0
PHP Warning:  readfile(): Unable to find the wrapper "https" - did you

PHP Warning:

Fortunately, the packaged version of Drush installed cleanly and works
fine.  The only mystery I have is why the errors only occur in the
jail.
