JROCK1980, the download page here: http://www.nvu.com/download.html
has the instructions you need to follow.
It says that Nvu is built with gcc3. You may have to install libstdc++.so.3.0.4 if you don't have gcc3 installed. I am using Nvu and this is how I got it going.
I don't have gcc3 so I needed libstdc++.so.3.0.4 installed. This is what worked for me.
1. Download libstdc++.so.3.0.4 from here: http://glazman.org/libstdc++.so.3.0.4
2. Copy it to /usr/lib
3. Run ldconfig
4. Change permissions on libstdc++.so.3.0.4
chmod 777 libstdc++.so.3.0.4
5. You do not need to install the program. Just run it from the directory that you untared it to.
I use this program and I like it. I have never used Frontpage or Dreamweaver so I don't know if it works like those or not. I like it though. Give it a shot, maybe you will also.
