I was thinking to pack the last guile-2.0.x however this will require the repack of 1.8.8 version.
No problem for the headers as they are properly isolated /usr/include/guile/1.8/libguile/__scm.h /usr/include/guile/1.8/libguile.h but what to do of /usr/lib/libguile.dll.a relocate it somewhere like /usr/lib/guile/1.8/libguile.dll.a Other suggestion/preference ? Regards Marco
