You may need to install the curl deveopment package. Usually on Linux
distributions, you have a base install (of curl, that would be the curl
executable, and libcurl for programs that link to it) and a separate
development install that includes the required headers.

-spc (Facing this very issue on my home system, which is running a
Linux distribution so old [1] that it's no longer supported.)

[1] Older than 20 minutes [2]

[2] I kid, but sometimes it feels like anything older than 20 minutes is
considered "ancient, you should try updating to the latest version,
then update again in case thing changed in the two minutes you spent
upgrading." [3]

[3] Which makes Lua a refreshing change.
