build issue: * Missing header file: HsBase.h

[Karel Gardas]

Duncan and Simon,

thank you very much for dealing with this. After adding -v3 to the 
ghc-cabal invocation it reported gcc error on HsBase.h due to missing 
math.h file, i.e. system/library/math/header-math package was not 
installed yet.

Thanks!
Karel
