Amos, Thanks for your response. I have the following already installed: gssapi related: 'cyrus-sasl-gssapi' 'cyrus-sasl-gssapi-32bit' 'libgssglue1' 'librpcsecgss' krb related: 'krb5' 'krb5-32bit' 'krb5-client' I also looked through the config.log where Markus indicated and found the following errors in relation to gssapi: configure:4188: checking gssapi.h usability configure:4205: gcc -c -g -O2 conftest.c >&5 conftest.c:54:20: error: gssapi.h: No such file or directory configure:4212: $? = 1 configure: failed program was: | /* confdefs.h. */ configure:4230: checking gssapi.h presence configure:4245: gcc -E conftest.c conftest.c:21:20: error: gssapi.h: No such file or directory configure:4252: $? = 1 configure: failed program was: | /* confdefs.h. */ configure:4299: checking for gssapi.h configure:4308: result: no configure:4188: checking gssapi/gssapi.h usability configure:4205: gcc -c -g -O2 conftest.c >&5 conftest.c:54:27: error: gssapi/gssapi.h: No such file or directory configure:4212: $? = 1 configure: failed program was: | /* confdefs.h. */ Any other ideas?

You could try installing the gssapi development libraries on your build machine. (sometimes called libkrb or libkrb5). Then re-running ./configure Amos -- Please be using Current Stable Squid 2.7.STABLE6 or 3.0.STABLE18 Current Beta Squid 3.1.0.13
