Turns out I needed also to set CPPFLAGS in order for AC_CHECK_HEADERS
in the /texk/dvisvgm/configure.ac to work as expected

Perhaps ok the latest patch to the TeXLive sources discussed at
http://tug.org/pipermail/tlbuild/2018q1/004094.html
was needed, I don't know.

Anyway I now get into the desired 

checking ghostscript/iapi.h usability... yes
checking ghostscript/iapi.h presence... yes
checking for ghostscript/iapi.h... yes
checking for gsapi_revision in -lgs... yes
checking Ghostscript version... "922"


But the process then ends with a report of 8 errors of similar nature

../../../../../texk/dvisvgm/dvisvgm-src/src/dvisvgm.cpp:78:48: error: unknown
      type name 'CommandLine'
static string get_transformation_string (const CommandLine &args) {
                                               ^

and 

../../../../../texk/dvisvgm/dvisvgm-src/src/dvisvgm.cpp:307:9: error: use of
      undeclared identifier 'CL'
                throw CL::CommandLineException(msg);


I assume I have messed up things with my 

$ export CPPFLAGS='-I/opt/local/include'

I must have overwritten some other config.

I don't want to occupy to much this mailing list though,
so I will only report later on in case I solve this
and do get my dvisvgm 2.3.3 with Postscript support

Best
