mkExprStmt not in scope in Parser.hs issue.

Hello,

I'm trying to get GHC HEAD compilation working on my freshly installed 
Solaris 11/x86 box and I'm trying to solve following error now:

gmake[1]: *** [compiler/stage1/build/Parser.o] Error 1
gmake: *** [all] Error 2


I'm bootstraping with GHC 7.4.2 and happy is 1.18.6 version and alex is 
2.3.5 if this is important. Is there any idea what causes this failure? 
The HEAD is as of today.

Thanks!
Karel
