Perhaps you do not have the "n64" system libraries set up correctly in 
userspace.
I have seen the "command not found" error when some fundamental 
libraries or the loader was missing.
Do you have a /lib64 & /user/lib64?
Run the file command on some of those libraries & see if they are n64 or 
n32 libs.
double check your ld.so.conf to make sure it points to every thing you need.
re run ldconfig if you change something.
