I have installed Ubuntu 14.04 using VirtualBox on my system. For my work, I wanted to install realpaver optimization software on Ubuntu. According to the installation instructions, I unpacked and then ran the command ./configure in the terminal. Unfortunately I encountered to this configuration error:

checking build system type... x86_64-unknown-linux-gnu
checking host system type... x86_64-unknown-linux-gnu
./configure: error: Sorry 
./configure: line 5199: exit: this: numeric argument required
./configure: line 5199: exit: this: numeric argument required

The software in question is: realpaver-0.4, an optimization software which I downloaded from here, and I'm using the 64-bit version of Ubuntu.

Can anyone help to solve this problem?
