clear command in my mac os terminal gives the following error

Question

dyld: Library not loaded: /opt/local/lib/libncursesw.5.dylib Referenced from: /opt/local/bin/clear Reason: image not found Trace/BPT trap

Answer 1

You probably need to recompile your MacPorts stuff.

$ port selfupdate

Answer 2

Let me guess... you put /opt/local/bin in front of /usr/bin, /bin, and /sbin or you probably set DYLD_LIBRARY_PATH and pointed it to /opt/local/lib, didn't you? That's a really bad idea. You should always put the system executables before the ones provided by MacPorts in your path. In addition, you should never set DYLD_LIBRARY_PATH, instead use DYLD_FALLBACK_LIBRARY_PATH.

Answer 3

This is how my bash_login looks like:

export PATH="/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:$PATH" export PATH="/usr/local/apache-maven-2.2.1/bin:$PATH" export PATH="~/.gem/ruby/1.8/bin:$PATH" export PATH="/usr/local/mysql/bin:$PATH" export PATH="/System/Library/Frameworks/JavaVM.framework/Versions/1.6/Home/bin:$PATH"

export PATH=/opt/local/bin:/opt/local/sbin:$PATH export MANPATH=/opt/local/share/man:$MANPATH
