gcc -shared build/temp.solaris-2.8-sun4u-2.1/_mysql.o -L/usr/local/mysql/lib/libmysqlcli ent.a -lmysqlclient -lz -o build/lib.solaris-2.8-sun4u-2.1/_mysql.so ld: fatal: library -lmysqlclient: not found ld: fatal: File processing errors. No output written to build/lib.solaris-2.8-sun4u-2.1/_mysql.so collect2: ld returned 1 exit status error: command 'gcc' failed with exit status 1 I think your system is missing an external package "mysqlclient" needed by zope. You have to download the binary for your plattform or compile it from source.
