Re^4: cpanm says OK but module not really installed

Digging deeper, Astro::SpaceElevator (from 2007), was broken by deprecation of the two-argument form of azel in Astro::Coord::ECI in 2013 (replaced by azel_offset in 2011).

Provide an Astro::Coord::ECI azel_offset() method, which takes, as its
optional second argument, an offset applied to the elevation, in
terms of the apparent radius of the body whose position is being
calculated. The two-argument version of the azel() method is now
deprecated, and will begin warning in the first release after March
1 2012.

Deprecations:
 
  * The two-argument form of azel() is now fatal.
