Hi there,

I found out that it is impossible to build the latest version of 
megatools in distributions with older versions of curl. I am building 
RPM packages for current versions of RHEL that ship curl versions 7.29, 
7.61 and 7.76 and all my builds have failed. So I added some conditions 
to commit 82c8421b31af77559c5c61b60955fe586c8ec5f2 to make the build go 
without errors. The patch is attached.


Regards,

Andrey K.
