[ecasound] JACK connection error in php scripts

Hi again,

I'm still trying to successfully port my application over to Mac OSX.
I have just about everything working, except for a very odd error.
Currently all of my scripts that call ecasound work fine from a
terminal window, but when I run them from a browser I get the
following error from ecasound:

ConnectPort: can't find mach server port name = jackdmp_entry.
503_default err = unknown error code
Cannot connect to server Mach port
jack server is not running or cannot be started

Jackd *is* running. I can dump the exact ecasound command line that
the script is running, and it works fine in a terminal window. The
same script, run via command-line php, works fine.

All of the jack binaries have been copied to /usr/bin (from /usr/local/
bin) so that they'll be in apache's default path (tried symlinking
first). They have the appropriate permissions & ownership.

Apache is running as a fully privileged user (the same user as the
console). The php exec() function successfully finds & runs the
ecasound binary, which is also located in /usr/bin.

Here's a complete dump of ecasound's output:
