It's the external file for darwin - ie. mac os x. I take it your on a 

windows system, so you have little use for it. Instead you need 

something like a file called fluid~.dll

 

I can't seem to find a .dll file for fluid~.  I've checked http://pure-data.cvs.sourceforge.net/pure-data/externals/footils/fluid/

but can only seem to find fluid.pd and fluid~help.pd.  Where else might I look?

 

      Thanks much,
