Vitali,

this needs to be followed up. When I ran the examples at Juelich, I had only 
unpacked the tarball that was identical to the one shipped to ANL (so I was 
told), added the examples directory and ran the commands as documented in my 
post.

If the /bgsys/local/ihpct-2.2.2 directory contents are the same, the 
difference must be somewhere else. Now that you (hopefully) received the 
tarball with the examples, could you please do me a favor and rerun exactly 
the same commands as printed in the post ? If it still breaks, I guess we 
have to compare OS versions between Juelich and ANL.

....or, I (admittedly) didn't specify -ldl - and it still worked in Juelich. 
So the linker must have been able to find dlopen, dlclose and dlsym 
regardless. Perhaps someone issued an appropriate ldconfig command ? Could 
you please run the following command and on your front end and compare the 
output ?

[pospiech at jugene2 ~]$ /sbin/ldconfig --print-cache | grep libdl
        libdl.so.2 (libc6,64bit, OS ABI: Linux 2.6.4) => /lib64/libdl.so.2
        libdl.so.2 (libc6, OS ABI: Linux 2.6.4) => /lib/libdl.so.2
        libdl.so (libc6,64bit, OS ABI: Linux 2.6.4) => /usr/lib64/libdl.so
        libdl.so (libc6, OS ABI: Linux 2.6.4) => /usr/lib/libdl.so
