Looking for Apache with mod_perl and mod_dav in HTTPD_DIR...
HTTPD_DIR /usr/apache exists, but does not contain httpd, mod_perl, or mod_dav

I couldn't find Apache!

Would you like me to build Apache for you? [Yn] OK, building Apache using src/build-apache-moddav...

+ set -a 
./build-apache-moddav: syntax error at line 12: `INSTALL_ROOT=${INSTALL_ROOT:-$' unexpected
Apache build failed! Please try again.
