|   UTF-8 support
|   No Unicode properties support
|   No just-in-time compiler support
|   Newline sequence is LF
|   \R matches all Unicode newlines
|   Internal link size = 2
|   POSIX malloc threshold = 10
|   Parentheses nest limit = 250
|   Default match limit = 10000000
|   Default recursion depth limit = 10000000
|   Match recursion uses stack
| OK~/Downloads/R-devel

That is a front-end tool. I don't even have it installed :)

| [snip]
| checking for pcre.h... yes
| checking pcre/pcre.h usability... no
| checking pcre/pcre.h presence... no
| checking for pcre/pcre.h... no
| checking if PCRE version >= 8.20, < 10.0 and has UTF-8 support... no
| checking whether PCRE support suffices... configure: error: pcre >=

| can anyone advise?

Ensure you have the corresponding -dev package. My system is now at the
current Ubuntu 18.10, not the Ubuntu LTS 18.04 you have -- but I have been
building R-devel on it about once every week or other week for years:
