Thanks. :) However, the patch from Francois is related to your question. locate prtypes /usr/include/seamonkey-2.0.14/prtypes.h /usr/include/seamonkey-2.0.14/nspr/prtypes.h The files are one and the same. The file size is 18744 bytes. The problem seems to be in jni_md.h where: #include <nspr/prtypes.h> /* needed for _declspec */ that the nspr directory is under /usr/include/seamonkey-2.0.14 (sym linked to /usr/include/seamonkey) rather than directly under /usr/include. I modified the patch: -#include <nspr/prtypes.h> /* needed for _declspec */ +#include <seamonkey/prtypes.h> /* needed for _declspec */ The package built without incident. Note: I have to use autoreconf -fiv rather than autoreconf. Thank you both. Why is this stuff so doggone hard...? P.S. I propose we update the README file to include this information. Darrell
