I installed the 2010.2.0.0 OS-X package today which was very easy. So far so
good except for the following problem when trying to install happstack-util
% cabal install happstack-util
... lots of stuff deleted ...
src/Happstack/Util/AutoBuild.hs:90:4:
Warning: A do-notation statement discarded a result of type ExitCode.
Suppress this warning by saying "_ <- waitForProcess ph",
or by using the flag -fno-warn-unused-do-bind
[13 of 19] Compiling Happstack.Crypto.MD5 ( src/Happstack/Crypto/MD5.hs,
dist/build/Happstack/Crypto/MD5.o )
ghc: could not execute:
/Library/Frameworks/GHC.framework/Versions/612/usr/lib/ghc-6.12.3/ghc-asm
cabal: Error: some packages failed to install:
happstack-util-0.5.0.2 failed during the building phase. The exception was:
ExitFailure 1
The ghc-asm executable exists -
% ls -l
/Library/Frameworks/GHC.framework/Versions/612/usr/lib/ghc-6.12.3/ghc-asm
-rwxrwxr-x 1 root admin 74344 Jun 11 11:42
/Library/Frameworks/GHC.framework/Versions/612/usr/lib/ghc-6.12.3/ghc-asm
- but the problem is that it uses an invalid perl location - namely
/opt/local/bin as shown below
% head -1
/Library/Frameworks/GHC.framework/Versions/612/usr/lib/ghc-6.12.3/ghc-asm
#!/opt/local/bin/perl
If I manually change it to the location of perl
% which perl
/usr/bin/perl
% head -1
/Library/Frameworks/GHC.framework/Versions/612/usr/lib/ghc-6.12.3/ghc-asm
#!/usr/bin/perl
then 'cabal install happstack-util' works.
Let me know if you need any more info,
Doug
