Thank you, Dr. Troyer. Now I am having problems trying to build ALPS. I downloaded the source package alps-2.2.b1-r7195-src.tar.gz from the webpage "
http://alps.comp-phys.org/mediawiki/index.php/Download_and_install_ALPS_2" and tried to build it, I was not successful at all. Then I downloaded the other source package alps-2.1.1-r6176-src.tar.gz from the same page and tried to build it, I ended up getting the same error message which reads "Error in configuration process, project files may be invalid."
Where can I find the correct source code for ALPS ?
