I think Florêncio refers to the linkage variant used to build the
dvisvgm binary. Ghostscript can be linked directly so that the
PostScript support is always available. In this case, the dvisvgm
command-line option --libgs is not present. The executable just requires
the properly versioned libgs, e.g. libgs.so.9.

If the libgs development files were not installed during the build
process, the resulting binary tries to load libgs.so via dlopen(), and
additionally provides option --libgs that can be used to give an
alternative filename.

At least, this is the default behavior of the original dvisvgm build
system. I'm not sure if the modified configuration files in TeX Live
offer the same build variants too.
