sorry but _I can reproduce it_ on OS X (I forgot to set umask of 0077):

andreas-mbp:OSELAS.Toolchain andreas$ umask

So the problem is this way:

- umask is 0077
- check_dirs_mkdir() will test to mkdir -m755 -p
  /opt/OSELAS.../<arch>.../gcc-<version>... -> fails
- check_dirs_mkdir() provide sudo mkdir ... (note! without -m755)
  -> success BUT:

  -> (note: this was patched bin/ptxdist with '-m755' in sudo mkdir
     path)
  -> therefore next commands can not access subdirs of
     /opt/OSELAS.Toolchain-2011.11.0/i586-unknown-linux-gnu/ (chmod,
     chown)

I guess the problem is directories on the way (= 'parents') are created
with default credentials -> umask has an effect. But the last directory
in path is set to given parameters (-m755).

Can you reproduce this too?

best regards
