Hi,
  first I installed libpano13 and Hugin by Synaptic package manager in 
Ubuntu 13.10. The installed libpano13 version is 2.9.18, and Hugin version 
is 2013.0.0.76c3df493921.

  Then I use hg to clone libpano13 and Hugin from SourceForge, and compile 
them successfully. This time libpano13 version is 2.9.19, and Hugin version 
is Pre-Release 2013.1.0.bdba8e67e8f7.

  However, after invoke "sudo make install" to install libpano13 and Hugin 
to "/usr/local" directory, there are some problems:

  1. I can't run previous Hugin installed through Synaptic by double-click 
in Unity interface of Ubuntu 13.10.  I can only run it by cd to "/usr/bin" 
and invoke "./hugin" to run it.

  2. If I invoke "hugin" directly or "/usr/local/bin/hugin", there is an 
error: "./hugin: symbol lookup error: 
/usr/local/lib/hugin/libhuginbase.so.0.0: undefined symbol: erect_hammer".

  Then I use command "ldd /usr/local/bin/hugin" to find what share 
libraries hugin app linked, and find this one: "libpano13.so.2 => 
/usr/lib/i386-linux-gnu/libpano13.so.2 (0xb6edc000)"

  It is strange, because when I use Cmake to configure Hugin, it find the 
libpano13 at "/usr/local/" directory (source compile installation) not 
"/usr/" (Synaptic installation).

  And, if I invoke the command 
"ylzhao@ylzhao-Lenovo:~/project/hugin/hugin.build/src/hugin1/hugin$ ldd 
./hugin", the output is: "libpano13.so.2 => /usr/local/lib/libpano13.so.2 
(0xb6f2e000)".

  As you can see, the output shows that hugin app compiled from source is 
linked with libpano13 installed by source compilation.

  Why after I install Hugin to "/usr/local" directory, the linked share 
library's path has been changed? 

  Thanks!
