in thread static linking demanded

A dirty hack for sure. On cygwin and possibly others you might have to use /. instead of // as // might indicate some network share. Devious things can even be done to defeat checksum schemes.

Dynamic linking is really when you can load at runtime a shared library; this is what perl needs for "use ...;". What is given by a "dynamic linker" like dld (/usr/lib/dlds.so for example) and the such is actually pretty static. The terminology varies a lot with the O.S. True dynamic linking is when a program can use the same API as the "dynamic linker". In perl code the true dynamic nature of a dlopen-like API means you can "use" to load and "no" to unload; this can be useful if you need to maintain a low memory consumption profile (using "use" and "no" as many times as necessary). Note that a process will not give back to the O.S the memory once taken but it can certainly reuse.
