Hi Matt, Yesterday, I installed PGPLOT and IFEFFIT from the tar ball on your web page on a clean (no previous installation of any of the XAFS software) Red Hat linux box. I used your script to install PGPLOT and was pleased that it worked just as expected. I had one small issue. When I tried to 'make' IFEFFIT, I got an error message saying that there was nothing for make to do. I realized that the configure step for IFEFFIT was writing out a Makefile but that the current directory had both a makefile and a Makefile. One makefile with a lowercase m and the other with a capital case M. So I removed the makefile and then IFEFFIT installed properly. Then I used the Horae script to install Ravel-ware, without any trouble. Overall the installation went really well...Good going. Shelly Kelly
