osx - Buliding an ARM cross-compiler with crosstool-ng on OS X -

i'm trying create cross compiler on mac raspberry pi, have managed configure, build , install crosstool-ng, when building arm-unknow-linux-gnueabi toolchain, fails. output of ./ct-ng build is:

update 1:

i have run 'grep' '-e' '^(# |)ct_' '.config' in crosstool-ng's bin directory , returns:

please help, i'm totally clueless :)

just figured it! crosstool-ng using own grep (strange, know), deleted own grep (which cannot process regular expression), , added symlink gnu grep built , located in usr/local/bin/grep.
