That's because 'libname test...' is actually a continuation of the "SAS
statement" beginning "#!/opt/bin/sas8/sas...".  That is:  SAS isn't
dropping the first line of the input program.

What's required is some sort of 'sasscript' shell wrapper which is what
your SAS programs invoke.  This would read the shebang line for options,
save them to be passed on to SAS, strip the first line, and invoke SAS
appropriately.
