NLS means Native Language Support and when you have it enabled (it is
not default), clamav can not be compiled as it shows following error:

Package clamav is missing dependencies for the following libraries:
libiconv.so.2

Also, it is required that package libiconv-full is compiled first/before
than clamav and then try to compile clamav.
