 How to compile with 32bit arch on 64bit machine:
 
-1) set the PAM_BIT environmental variable to "-m32"
+1) set the PAMELA environment
+
+2) source set_env_comp.sh
+
+3) set the PAM_BIT environmental variable to "-m32"
 
-2) enter the directory "event" 
+4) enter the directory "event" 
 
-3) mv Makefile Makefile.orig
+5) mv Makefile Makefile.orig
 
-4) mv Makefile.compile32biton64bitarch Makefile
+6) mv Makefile.compile32biton64bitarch Makefile
 
-5) edit Makefile and set the correct path for these two lines, repeated twice on lines 103/104 and 117/118 
+7) edit Makefile and set the correct path for these two lines, repeated twice on lines 103/104 and

 the correct path depends on your setup.
