Building toolchain with crosstool-ng on Mac OS X 10.6.2 (SL) - libtool error

Hi Titus, Yann and all,

I wrote a short script for MacOS SL and crosstool-ng-1.6.0. I got an error with libtool, because the crosstool-ng/configure wrote:

  Checking for 'libtool'... no
  libtool 1.5.26 or above was not found

I used the newest version of libtool 2.2.6b_0. Script and log-file see attachment.

Can anyone please help me?
