It is a slow day, and those who really know the answers may not
be around. So here goes.

On my Red Hat System (noodle), I get:
baron at noodle /usr/lib > "ls" -l libg2c*
lrwxrwxrwx 1 root root 15 Apr 8 13:57
libg2c.so.0 -> libg2c.so.0.0.0
-rwxr-xr-x 1 root root 109976 Feb 25 2003
In other words, it is linked to libg2c.so.0.0.0. Also, where
does it come from?

baron at noodle /usr/lib > rpm -ql libf2c
In sum, it seems you need the rpm called libf2c.

I have done this, and I do recommend it if you have a reasonably
fast computer. But in this particular case, based on
guesstimation from the name of the missing rpm, I bit you would
need it anyway.
Another way to find missing rpms is by typing in the name of the
relevant file in the search section of

It is better to ask one question per email. If this were the
only one, I wouldn't answer. But I have noticed that Rweb uses
Perl with R: http://www.math.montana.edu/Rweb/
There is also a CGIwithR package that I haven't tried, and I
don't know what it does.
