Can't use invert(), function $ADJOINT is undefined

Maybe some other package I have loaded is overriding
the definition of invert().

Is there a way to tell which file invert() is being
called from, sort of the equivalent of the UN*X
"which" command?

I tried doing a trace(invert), but it only told me
when it was entering the function, and then printed
out the same error message.

Here are the contents of my maxima-init.mac file:

load(absimp) $
load(fourie) $
load(functs) $
load(fft) $
sinc(x) := block([], if (x = 0) then return(1), sin(x)
/ x) $
j : %i $
pi : %pi $
