I have just had an error when trying to reinstall webalizer in DirectAdmin.

Libgd error was echoing. So I was looking for reproduce problem and found a solution.

https://fedoraproject.org/wiki/EPEL // install repo for gd-devel

yum install gd-devel // install gd

./build webalizer

###### and voila
rm -f /usr/bin/webazolver
ln -s webalizer /usr/bin/webazolver
/usr/bin/install -c -m 644 webalizer.1 /man/man1/webalizer.1
/usr/bin/install -c -m 644 wcmgr.1 /man/man1/wcmgr.1
rm -f /man/man1/webazolver.1
ln -s webalizer.1 /man/man1/webazolver.1
/usr/bin/install -c -m 644 sample.conf /usr/etc/webalizer.conf.sample
[root@online custombuild]# webalizer
Webalizer V2.23-08 (Linux 3.10.0-862.14.4.el7.x86_64 x86_64) English

That’s it.
