Web2C based TeX distributions (you have one such according to pdfTeX banner) 
use configuratin file texmf/web2c/texmf.cnf (or vartexmf/web2c/texmf.cnf -- 
various TeX distributions may differ in this point). All searching paths are 
set here. For tex is it usually 

TEXINPUTS.pdftex   = .;$TEXMF/{pdftex,tex}/{plain,generic,}//
TEXINPUTS = .;$TEXMF/tex/{generic,}//

It means that pdftex searches only in 'pdftex' and 'tex' subdirectories of the 
texmf tree. So one solution would be to move therion tex to texmf/tex/. 
(You had good luck to copy metapost files to texmf/metapost/)

It's also possible to modify TEXINPUTS to point to directory outside of texmf, 
so there would be no necessity to copy therion files in texmf directory. Try

TEXINPUTS = .;$TEXMF/tex/{generic,}//;/cave/therion/lib/tex//

or similar. 

Run texhash after changing texmf.cnf file.
