HI, I was trying to install R package 'culr' on a RHEL machine. I got the following errors.

After this, I manually compiled the curl.so and ran ldd on it. The following is the result:

Any idea why curl.so can't be loaded? Thanks for any help!

It is resolved. The LD_LIBARY_PATH doesn't include the correct path.
