Hi again,

and sorry to come up with so many installation issues today.
I used the installer from Csound5.06-x86_64d.tar.gz
After installing 5.06 successfully into the system dirs, i get the following warnings when running csound:

WARNING: could not open library '/usr/local/csound64_64/libwidgets.so' (/usr/local/csound64_64/libwidgets.so: undefined symbol: _ZN2Fl4lockEv)
WARNING: could not open library '/usr/local/csound64_64/lib_scoregen.so' (lib_csnd.so: cannot open shared object file: No such file or directory)
WARNING: '/usr/local/csound64_64/libcsnd.so' is not a Csound plugin library

i found lib_csnd.so required by lib_scoregen.so in here: /usr/local/csound64_64/frontends/

the ususal csound instruments do work, but:
the fltk opcodes don't run (because of libwidgets.so?),
and tclcsound.so seems to be missing.
