deleted the software folder - PEBKAC

[plik]

Hi,

my name is George, I am not a very skilled Linux or OSX (Terminal) user, 
and english is not my native language.

My OS is 10.6.8 64bit

Today I installed Macports for the subsequent installation of ARB. 
Everything went really fine until I tryed to start ARB. But actually, 
this is another problem. Herewith, I would like to ask for help for the 
probably stupid things I did to solve the "ARB won't work" problem.

I thought "maybe it is a good idea to re-install arb with Macports". 
Here is what I did:

###########
luis:~ plik$ sudo port install arb
--->  Computing dependencies for arb
--->  Cleaning arb
--->  Scanning binaries for linking errors: 98.7%
Warning: Error parsing file /opt/local/share/arb/lib/ARB.bundle: Error

luis:~ plik$

I thought "maybe it is a good idea to rm -rf the arb folder in 
/opt/local/share/". I did so.

Then, I tried again to install ARB with Macports.

I am completley lost. I don't know what to do and also why I should this 
or that.

It would be great, if someone knows an answer.


Thanks for reading this mail!

George
