 When I was trying to install the gnuplot via macports, i.e.

 {{{
 sudo port clean gnuplot
 sudo port install gnuplot
 }}}

 I got the following messages:

 {{{
 Error: org.macports.build for port gnuplot returned: command execution
 failed
 Please see the log file for port gnuplot for details:
 /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_math_gnuplot/gnuplot/main.log
 To report a bug, follow the instructions in the guide:
     http://guide.macports.org/#project.tickets
 Error: Processing of port gnuplot failed
 }}}

 After inspecting the main.log file, I found the following error message:

 {{{
 :info:build dyld: Library not loaded: /opt/local/lib/libpng15.15.dylib
 :info:build   Referenced from: /opt/local/lib/libpangocairo-1.0.0.dylib
 :info:build   Reason: Incompatible library version:
 libpangocairo-1.0.0.dylib requires version 31.0.0 or later, but
 libpng15.15.dylib provides version 30.0.0
 }}}

 How can I solve this problem?

 Please remember to set the port field and cc the maintainer. You don't
 need to cc yourself. Please try to use WikiFormatting when posting in
 trac.

 Please provide the output of `otool -L /opt/local/lib/libpng15.15.dylib`
 on your system.
