[Eric] eric4 and ruby

[Josep Ferrandiz]

Detlev,

I have attached the file and have been able to isolate the lines that cause the problem:
$stderr.reopen("/dev/null", "w") and $stderr.sync = true.
They are in the function add_R_lib() that turns off $stderr while an R library is loaded that generates a bunch of warnings when loaded.
Thanks
Josep
