Nginx stable package gives wrong symlink of modules-available/

I've upgrade to the latest nginx-full (1.10.1-3+trusty0) via ppa:nginx/stable. But I find the wrong symlink of modules-available/.

 ls -l /etc/nginx/modules-enabled/*
lrwxrwxrwx 1 root root 57 10月 16 14:27 /etc/nginx/modules-enabled/50-mod-http-auth-pam.conf -> /usr/share/nginx/modules-available/mod-http-auth-pam.conf
lrwxrwxrwx 1 root root 53 10月 16 14:26 /etc/nginx/modules-enabled/50-mod-http-echo.conf -> /usr/share/nginx/modules-available/mod-http-echo.conf
lrwxrwxrwx 1 root root 54 10月 16 14:27 /etc/nginx/modules-enabled/50-mod-http-geoip.conf -> /usr/share/nginx/modules-available/mod-http-geoip.conf
lrwxrwxrwx 1 root root 61 10月 16 14:27 /etc/nginx/modules-enabled/50-mod-http-image-filter.conf -> /usr/share/nginx/modules-available/mod-http-image-filter.conf
lrwxrwxrwx 1 root root 60 10月 16 14:27 /etc/nginx/modules-enabled/50-mod-http-subs-filter.conf -> /usr/share/nginx/modules-available/mod-http-subs-filter.conf
lrwxrwxrwx 1 root root 62 10月 16 14:27 /etc/nginx/modules-enabled/50-mod-http-upstream-fair.conf -> /usr/share/nginx/modules-available/mod-http-upstream-fair.conf
lrwxrwxrwx 1 root root 60 10月 16 14:27 /etc/nginx/modules-enabled/50-mod-http-xslt-filter.conf -> /usr/share/nginx/modules-available/mod-http-xslt-filter.conf
lrwxrwxrwx 1 root root 48 10月 16 14:27 /etc/nginx/modules-enabled/50-mod-mail.conf -> /usr/share/nginx/modules-available/mod-mail.conf
lrwxrwxrwx 1 root root 50 10月 16 14:27 /etc/nginx/modules-enabled/50-mod-stream.conf -> /usr/share/nginx/modules-available/mod-stream.conf

I think the /usr/share/nginx/modules-avaliable/* should link to /etc/nginx/modules-avaliable/ , not /etc/nginx/modules-enable/.
