dsss.conf prebuild being ignored

[torhu]

I have this dsss.conf, in a subdir below the main one.  The problem is 
the the prebuild line (righ below "version (Posix)") is ignored.  Can 
anyone spot a syntax error that might be causing this?  The echo command 
line works fine when I run it in the shell.  allegro-config is just a 
script that returns libraries to be linked with.
