This post contains suggested OS shell commands. I have no idea if they'll 
work on your system in the form presented, or if they'll trash your 
system completely. Use these commands at your own risk. I might have 
accidentally slipped a couple of commands in that will erase your hard 
disk, so check all the suggested commands before you run them.

Is it possible you have two versions of the library installed? One that 
has the relevant symbols (in /usr/lib/libiconv.2.dylib) and one that 
doesn't (in /Applications/MAMP/Library/lib/libiconv.2.dylib), and that 
the one that the php shell is picking up isn't the same one as when you 
run git from the OS yourself?

The quick fix - create a link from where it's looking for the library to 
where the library really is:

open a command shell

Check that "/usr/lib/libiconv.2.dylib" exists:

$ ls /usr/lib/libiconv.2.dylib

Check that "/Applications/MAMP/Library/lib/libiconv.2.dylib" doesn't 
exist:

$ls /Applications/MAMP/Library/lib/libiconv.2.dylib

if ("/Applications/MAMP/Library/lib/libiconv.2.dylib" exists):

See if it's the same size, date, md5sum[1] as "/usr/lib/libiconv.2.dylib"

[1] You're expected to know how to do this, if you don't, you shouldn't 
have opened the command shell in the first place!

Decide what to do next yourself. You might decide to copy one version of 
the library over the other one, or delete one and then follow the "else" 
branch below, or do something else - but it's up to you to figure out how 
to solve the problem. I'd probably rename "/Applications/MAMP/Library/lib/
libiconv.2.dylib" to something like "/Applications/MAMP/Library/lib/
libiconv.2.dylib.old" and then create the link below.

else:

Create a symlink from the non-existant file to the existing one:

$ ln -s /usr/lib/libiconv.2.dylib /Applications/MAMP/Library/lib/
libiconv.2.dylib

endif;

Note as these are commands you'd be issuing in the shell, you might need 
to su root or something (I'm not that familiar with OSX) to get the 
permissions needed.
