I'm using solus and everything is fine as a regular user but now I'm trying to install a development environment I have some issues with postgis postgres extension, since you have not any precompiled package had to build by my self, however I'm getting after ./configure command :

checking for xmlInitParser in -lxml2... no
configure: error: could not find libxml2

and I have libxml2-devel installed.

any help appreciated

do you have the -c system.devel installed?
