I must have done something silly with the DYLD_LIBRARY_PATH. This is an error I got when running svn

$ svn info 
dyld: Library not loaded: /usr/lib/libpq.5.dylib
  Referenced from: /usr/bin/svn
  Reason: image not found
Trace/BPT trap: 5

Run it in a new shell and the problem goes away.

Just installed otx, an OSS implementation of otool

Just learn something new (to me) about bash:

1) Anonymous function

2) local (to subroutine) variable

Tried to install erlang. Got this error message

$ brew install erlang

You can try again using `brew link erlang'

Tried the following but did not work

$ brew cleanup erlang; brew unlink erlang; brew link erlang

sudo unlink and link fixed the issue finally
