I'm in the process of upgrading an asterisk to 1.2.10 and started by upgrading libpri-1.2.3 (make & make install) and zaptel (make & make install). Was about to install asterisk, but doing a "ls" I get the following error: ls: relocation error: /lib/libpthread.so.0: symbol _h_errno, version GLIBC_2.0 not defined in file libc.so.6 with link time reference How can compiling and installing zaptel and libpri cause errors like this in other programs ? Running a gentoo with 2.6.11 Thanks
