Trouble compiling fibon

[David Feuer]

I'm trying to compile the fibon benchmark suite, but I'm getting a
non-specific permission error. Can anyone give me a clue?

== make boot - --no-print-directory;
 in /home/dfeuer/src/ghc-slowmod/nofib/fibon/Hackage/Bzlib
------------------------------------------------------------------------
//     Codec/Compression/BZip/Stream.hsc
make[2]: execvp: //: Permission denied
make[2]: *** [Codec/Compression/BZip/Stream.hs] Error 127
Failed making boot in Bzlib: 1
