The obvious thing that comes to mind is file permissions. :-)

If you want the hacker way to verify the file is getting opened
properly or not, you could run strace and look for the return code on
the stat() or stat64() system call

write(5, "#  Trying \"/home/rocky/.ddd/vsll"..., 44) = 44
stat64("/home/rocky/.ddd/vsllib/ddd.vsl", 0xbf8d1a5c) = -1 ENOENT (No such file 
or directory)
stat64("/home/rocky/.ddd/vsllib/ddd.vsl", 0xbf8d1a5c) = -1 ENOENT (No such file 
or directory)
write(5, "#  Trying \"/usr/local/share/ddd-"..., 64) = 64
stat64("/usr/local/share/ddd-3.3.12-test6cvs/vsllib/ddd.vsl", 
{st_mode=S_IFREG|0644, st_size=8209, ...}) = 0
