Help--ORBit-0.5.4 Installation

["Sammon, John G." <jgsammon TASCNTP0 READ TASC com>]

I'm not sure what's happening here, but when I run a make, I'm getting the
following:

.....

It took me long enough to remeber that the .libs directory wouldn't show up
in a 
regular ls -l.  Anyway, it appears that the problem is generated in the
libIDL 
subdirectory.  Any ideas how/where these symbols should have been defined?
