Are you wanting to modify the quantmod package or simply install it?
If the latter, the install.packages() command from within R should
take care of everything for you.

If looking to modify/extend the quantmod functionality, take a look at
the devtools package developed by Hadley Wickham. It tries (from what
I hear, successfully) to make the write-install-check cycle of package
development much faster.

Cheers,
