[R-SIG-Mac] libcurl

[peter dalgaard]

It doesn't usually happen on 10.13.6... Best guess is that somehow you are picking up an older library (e.g. in /usr/local/lib) even if you are using curl-config from a newer version.

The detective work needed could take off from config.log, region around this:

configure:39937: checking if libcurl is version 7 and >= 7.22.0
configure:39966: gcc -arch x86_64 -o conftest -g -O2   -I/usr/local/include  -L/usr/local/lib conftest.c -lcurl -lpcre -llzma -lbz2 -lz -licucore -lm  -liconv >&5
configure:39966: $? = 0
configure:39966: ./conftest
configure:39966: $? = 0
configure:39976: result: yes

That's for a succesful build, a failed one will usually give more info including the failing program code.
