[R] Compiling R with zlib in non-standard location

It has been a while since I have worked on RH based systems, but looking at Martyn's reply, which includes:
CFLAGS="-g -O2 -I/path/to/my/headers" \
and references to the R Installation and Administration manual sections B3.3 and B7, if you used the lines verbatim as above, you will likely need to explicitly 'export' the two flag variables. Thus try:
export CFLAGS="-g -O2 -I/path/to/my/headers" \
export LDFLAGS="-L/path/to/my/libs" \
Using 'export' will ensure that the environment variables are also passed down to child processes started within the current shell session, which may be where it is failing.
See if that works. If not, subscribe to and post a new thread to R-SIG-Fedora, as there will be a focused audience there.
