Hi,
I am going to install nil  on my Mac OS X 10.8.5 following as per
suggestion in website. which gcc
/usr/bin/gcc
and

which gfortran
/usr/local/bin/gfortran

Rams-MacBook-Pro:Desktop root# gcc -v
Configured with:
--prefix=/Applications/Xcode.app/Contents/Developer/usr
--with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
Target: x86_64-apple-darwin12.5.0
Thread model: posix

Rams-MacBook-Pro:Desktop root# gfortran -v
Using built-in specs.
COLLECT_GCC=gfortran
COLLECT_LTO_WRAPPER=/usr/local/libexec/gcc/x86_64-apple-darwin12.5.0/4.8.1/lto-wrapper

Configured with: ../gcc-4.8.1/configure --enable-languages=c++,fortran
Thread model: posix
gcc version 4.8.1 (GCC)

but,
locate  libgfortran.3.dylib

WARNING: The locate database (/var/db/locate.database) does not exist.
To create the database, run the following command:

  sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.locate.plist

Please be aware that the database can take some time to generate; once
the database has been created, this message will no longer appear.
;--------------------------------------------------------------------------------------------------------

As per running ncl under machos (website) if libgfortran.3.dylib is
absent then download for new version but gcc-4.8-bin.tar and
gfortran-4.8-bin.tar are most latest one.

Appreciate any help on it.

Thank You.
