I finally got around to downloading Ive's spectral render rack. When trying to
render the sample scene Ring.pov, I got a missing semicolon error. The command
line and message output are reproduced here:

==== [Parsing...] ==========================================================
Spectral rendering: wavelength 380nm
File 'spectral_materials.inc' line 246: Parse Error: All #declares of float,
vector, and color require semi-colon ';' at end if the language version is set
to 3.5 or higher. Either add the semi-colon or set the language version to 3.1
or lower.
Fatal error in parser: Cannot parse input.
Render failed
_______________________________________________________________________________
There are clearly sufficient semicolons on and before line 246. As far as I can
tell, the call seems to originate with the C_Average call on line 75 of
Ring.pov, but I cannot be completely sure. (I will so be ecstatic when the dev
team implements the call stack postmortem.) A bit of analysis indicates that
the parser does not interpret SpecData1 as an array, so when it sees the '[', it
thinks that the r-value is finished. As I am still trying to figure out how
this package works, I'm not in a position to figure out exactly what went wrong.
Prism.pov produces the same error, but ColorChecker.pov renders flawlessly.
