[texhax] Any PPCHTeX users out there?

[Karl Berry]

Hi Rodolfo,

    where the executable file `tex' is present, everything goes fine; 
    instead, if I run TeX from my home directory, I get the message: 

Obvious question, but are you running the same tex binary in both cases?
Did you set PATH to include the directory with that `tex' before others?

    ! TeX capacity exceeded, sorry [text input levels=15]. 

Any indication as to what files it is reading?
The log file might be helpful, for a start.

Cheers,
karl
