Dear GHC developers,
I am testing this fresh ghc-7.0.0.20101028
on Debian Linux, i386-family.
Making it from source by ghc-6.12.3 is all right.
Then, making it from source by itself reports

Why cannot it make itself?
genprimopcode now needs -package array to build. We'll fix this in the
build system but it raises an interesting point that we probably haven't
publicised much.
Previously we linked the haskell98 package by default, which also caused
its dependencies (include array) to also be linked, but in 7.0.1 we
don't link haskell98 by default, only base.
If you're using --make (which is now the default in 7.0.1), you won't
notice any difference, because all package dependencies are
automatically linked, so this only makes a differences in "one-shot"
mode where you compile each module to .o files first and then link by
saying
ghc Main.o Foo.o Bar.o -o prog
So if you're doing this, and the program has dependencies on modules not
in base, then you need to list them explicitly, e.g.
ghc -package haskell98 Main.o Foo.o Bar.o -o prog
This is part of moving from Haskell 98 to Haskell 2010 as our default
base language.
Cheers,
Simon
