I have been having difficulty in compiling mpich-1.2.0 with romio.  When 
romio compiles, nfs + ufs are the only filesystems created.  I assume these 
must be the defaults.   These are the options I sent to the configure script.
./configure -c++=pgCC -cc=pgcc -fc=pgf77
-rsh=rsh --with-romio="-file_system=pvfs 
-cflags=-I/home/makleske/pvfs/include" -lib="-L/home/makleske -lminipvfs" 

I even tried single quotes. I also tried compiling mpich with no romio 
support then I compiled romio seperately.  Everything compiled nicely but 
when I executed btio-full I received. 

 NAS Parallel I/O Benchmarks -- BTIO Benchmark
 No input file inputbt.data. Using compiled defaults
 Output file name:                                /pvfs/btio.full.out

Finally I tried LAM.  It was able to compile romio correctly but I received a 
runtime error when running btio-full.  I don't have the error saved but it 
had to do with invalid datatypes in ADIOI_Flatten.
