Did you compile the entire 1.4.2 release? There has been a fix for  
Redhat since there is a problem in the kernel for the dig and the  
nslookup command when using popen. Our fix in 1.4.2 release also  
changed the configure script to pick up this scenario., but if you  
just took the check_dig.c file and compiled against the 1.4.1  
release, this would not pick up the fix.
