[texhax] bibtex error message

[Karl Berry]

    $ bibtex report
    bibtex: Need exactly one file argument.

This is utterly bizarre.

Do you have an alias or shell script masking the bibtex binary?  Do
"type bibtex" (I guess you're using bash from the prompt) to make sure
you're invoking what you seem to be.  Or specify the
/full/path/to/bibtex report.  Finally, does bibtex --help print a help
message?

Mysteriously yours,
