haskell - Problems building nofib/fibon -

when building fibon benchmarks under nofib benchmarks suite got several permission denied messages, 1 below:

== make boot - --no-print-directory;  in /h/ywang30/nofib/fibon/hackage/bzlib ------------------------------------------------------------------------ //     codec/compression/bzip/stream.hsc make[3]: execvp: //: permission denied make[3]: *** [codec/compression/bzip/stream.hs] error 127 failed making boot in bzlib: 1 

i'm building suite advised on ghc wiki page. default fibon not included in build , edited mk/boilerplate.mk (line 35) include (which works parallel benchmarks). know that, wiki correct way should editing ../mk/build.mk , ../mk/config.mk, there's no line involving nofib in either file. doing wrong, or bug?
