dependency problem

I'm running Debian Buster with Openresut 1.15.8.3-1 from the official repositories.
Installing this module gives the following output:

Package openresty/lua-resty-lrucache 0.08 installed successfully under /usr/local/openresty/site/ .
ERROR: ngx_http_lua = 0.10.13 required but found ngx_http_lua 0.10.15 according to resty.

your dist.ini seems to depend on a specific version of ngx_http_lua:

ngx_http_lua = 0.10.13

Wouldn't it be better to have de dependency on ngx_http_lua >= 0.10.13?

Start with dist.ini and inspect the ngx_http_lua dependency declaration shown in the issue. Reproduce the opm get slact/durpina installation on the reported OpenResty setup, then verify that the dependency metadata accepts the installed ngx_http_lua version without the reported error.
