-sh: find: not found

[wirespot]

I get this kind of error message for various executables from packages downloaded from Oleg's feed:

-sh: find: not found

find is in /opt/bin, /opt/bin is in my PATH and if I run "which find" I get /opt/bin/find. But trying to run /opt/bin/find or find or ./find all gives the above "not found" error. What gives?

I've started with the "classical" feed:

src unslung http://ipkg.nslu2-linux.org/feeds/unslung/wl500g

But later I've changed that to Oleg's feed:

src unslung http://ipkg.nslu2-linux.org/feeds/optware/oleg/cross/stable

And after upgrading or installing some packages from Oleg's I got this problem. Have I mixed packages from the two repositories or something? How would I go about fixing this?

Nevermind, I figured it out on my own: I had switched to Oleg's feed and forgot to install his uClibc package. I had to download the .ipk manually and install it with ipkg and after that everything started working again.
