Okay, I installed the "curl" versions, how do I edit the 
activating shell scripts of DMD and LDC that they'd work as if 
they were installed "normally"? I don't have the time, not the 
capacity to test my libraries with multiple different compiler 
versions, and document any oddities between them (and I almost 
never need it thanks to D).
