Changes between Initial Version and Version 1 of Ticket #51516, comment 113

initial	v1
1	1	Come to think of it ... before my current hack I used a `DYLD_LIBRARY_PATH` and/or `DYLD_INSERT_LIBRARIES` (and their Linux equivalents) to overload the system libcurl with the one from MacPorts. That was tricky because of how MacPorts controls the environment and because of the side-effects `DYLD_LIBRARY_PATH` can have.

3		I think a rewrite of `curl.c` can be avoided if we can simply try to `dlopen` an appropriate (tested etc) libcurl from the `port` driver command before it loads the Pextlib extension. It looks like this would require either a glue library that provides at least a stub Tcl package loader function (`Curl_Init()`~~) or else adding a Tcl extension (https://wiki.tcl-lang.org/page/dlopen+extension)~~.

A glue library seems a little more appropriate.
