Add the following to the above:

1) Copied (not symlinked) the entire pspell (and ispell wrapper) binaries
(which are really called aspell) to Safe_mode Binary directory. Fixed up any
paths within scripts to be absolute. (CHECK) 

1A) Tried completely absolute and relative path specifications within the
imp/config/conf.php setting. (CHECK)

2) Ensured owner/group privs on all pspell files matched horde/imp .php
pages and were legible to the webserver's processes (CHECK)

3) Added LANG and LANGUAGE to the allowed environment vars to be altered by
PHP... (CHECK) [along with "TZ", this silences warnings successfully]

4) Configured the imp/conf.php file's usage of the spell check command to
ensure ISPELL compatibility mode (implicitly expected by the code) is
enabled, and echo'ed command lines to a text file to ensure they met
expectations. (CHECK)

5) Enlarged memory and execution time limits past reasonable prudence.

Results: 

Safe_Mode ON:: No spelling check functionality at all.  No errors logged in
either webserver or horde logs.  You can click on the spell-check button,
but it always says everything's spelled correctly.  It's as if the command
is executed, but generates no output and returns with a 0 status (no-error).
It was at about this time I had to be pressing on to my daily spleen flensing.

Safe_Mode OFF:: Clicking on the spell check button has the desired effect,
showing all spelling mistakes taking into account the user's language
preference.  Proper English users don't have to suffer "color", etc.
