In principle rootcint depends on LD_LIBRARY_PATH being correctly set.
However, it is not needed to run the interactive root module since
the front-end program "root" sets LD_LIBRARY_PATH before exec'ing
"root.exe" (the actual root). On the other hand, whem directly calling
root.exe you'll need a correct LD_LIBRARY_PATH. If you build yourself
root from source you can add "-rpath $ROOTSYS/lib" to the link statement.
(on GNU/Linux systems). In that case LD_LIBRARY_PATH is not needed
(good when root is centrally installed). Another alternative, on Linux,
for centrally installed root is to add $ROOTSYS/lib to /etc/ld.so.conf
(don't forget to run ldconfig afterwards).

Cheers, Fons.
