[OS X TeX] updmap command not found

[Robert Blackstone]

Hi Everybody,
On my iMac, under OSX 10.5.3, on which my TeX installation in general
seems to work perfectly, nevertheless in Terminal I cannot use updmap,
nor kpsewhich, nor texhash and the like. In all cases I get the
message "command not found".
I should perhaps add that I did not freshly install TexLive on this
iMac but instead carried it over from my Powerbook under OSX 10.4.11
(where everything, including updmap etc., works fine).
Does anybody have a suggestion as to what I should do?
