I don't understand you here. The only think is that we want to hardcode
a full path to fricas in that file and fall back to "fricas" (without
path) if that executable is not available.
So I would define a customizable variable like
(defcustom fricas-executable
"@exec_prefix@/fricas"
"The command to run FriCAS."
:type 'file
:group 'fricas)
(well the @...@ will not exactly work like that, but more to that tonight)
and then another function
(defun fricas-run-command ()
(if (executable? fricas-executable) fricas-executable "fricas")
)
which checks whether fricas-executable is actually executable (and
returns this string) and falls back to "fricas" (and returns this
string) if it is not the case.
(I hope you could send me the actual name of my dummy function
"exectuable?".)

With the above that should work fine.
