Can I report that all the packages required to build gretl on a Raspberry Pi are available on the Raspbrian repository? I compiled the git version of gretl (2019d of 2019-09-30) on a Raspberry Pi 2. . (gcc-doc was not available but configure finished without it.) Make was slow (> 1 hour). Once installed, gretl loads fast and the responses to the few examples that I ran were also good. Thus all the mathematical and other libraries required to compile gretl on ARM 7 are available in the Rasbrian repository. The current Pi 4 should be much faster.
