Configure is supposed to check whether there is a working ctangle exe in PATH already. At least, that is what I remember.  But I cannot actually test anything on the ipad right now.

What I don't understand is why it cannot find texmf.cnf because the
file is there.

But anyway ... with some further manual compilation (simply running
"make" elsewhere in the tree after the failure) I somehow stumbled
upon

Undefined symbols:
  "_fopen$UNIX2003", referenced from:

and http://www.cocoawithlove.com/2009/09/building-for-earlier-os-versions-in.html
suggested me to add
    -isysroot /Developer/SDKs/MacOSX10.5.sdk -mmacosx-version-min=10.5

I thought the second argument was equivalent to
    export MACOSX_DEPLOYMENT_TARGET=10.5
but apparently adding -mmacosx-version-min=10.5 solved the problem.

Please don't ask me how this was related to the failure to find texmf.cnf.
