Sorry, I cannot run apxs. Possible reasons follow:
1.Perl is not installed
2.apxs was not found. Try to pass the path using --with-apxs2=/path/to/apxs
3.Apache was not built using --enable-so (the apxs usage page is displayed)
The output of /usr/bin/apxs2 follows:
./configure: line 6311: /usr/bin/apxs2: No such file or directory

checking for the location of zlib… /usr
checking for pkg-config… (cached) /usr/bin/pkg-config
checking for libzip… not found
