If I build with the new binutils installed, I get the same permission problem as above. If I build with the older version, there is no problem. I believe, but cannot verify at the moment that everything runs fine under the new binutils, it just does not work if the newer binutils is installed when I compile matplotlib. I will attempt over the weekend to get a simpler testcase built. Gary Zablackis __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
