Hello Frans, What always worked for me is to omit -static and instead use full paths to the .a files when linking (without -l): g++ -O2 -o hello hello.C /usr/local/lib/libwthttp.a /usr/local/lib/libwt.a ...
There may be some option of ld or gcc that avoids static linking for some libraries, but I don't know that by heart.
