Probably not impossible, but hardly worth the effort.
This is the most easy :
# yum -y install xfig
which will install xfig and the dependency transfig.
If no yum, there are packages : http://rpm.pbone.net/index.php3
> > Search > "Advanced Search" , keyword = xfig-3
... for all Fedora's and RH EL 4, EL 5,
including 'src.rpm's to create rpm with 'rpmbuild'.
