问题
As there is no Windows binary for v1.95-4.3 yet, I need to install/compile the RCurl package from source on Windows 8.1. (64 bit).
Could someone tell me
- Which version of cURL I need
- Where the various files such as
libcurl.dlletc. need to be placed exactly
Does the x64 directory mentioned in the error message below correspond to the x64 directory of the R installation?

Thanks a lot!

Looks like the RCurl v1.95-4.3 binary file for Windows has been uploaded to CRAN as of this morning. I was dealing with the exact same issue as you, and after building the binary file from source, all was well with my usage of RCurl again!
http://cran.r-project.org/web/packages/RCurl/index.html
install.packages("RCurl_1.95-4.3.zip", repos=NULL, type="source")

Not sure which version of cURL you have on your machine, but as it states on this website that version 7.37.0 seems to work for Windows 8
EDIT You can try this manual download. It specifies the .dll files you mentioned and is compatible with 64 bit http://www.stats.ox.ac.uk/pub/RWin/bin/windows/contrib/2.15/
