In the current CRAN version of the package, the stated dependencies are
in wild disagreement with each other:
https://github.com/RobinHankin/gsl/issues/17

DESCRIPTION says that GSL >= 2.1 is required, ./configure error message
asks for >= 1.16, but the actual test is for GSL >= 2.5:
https://github.com/cran/gsl/blob/78211300997576f89fae61caada64483dc2538d1/configure.ac#L27

(Well, it's intended to test for >=2.5, but seems to test for any minor
version of 5 and above instead.)

I'm not sure which GSL features the package actually makes use of. You
can either try patching ./configure to actually check for GSL >= 2.1
and rebuilding the package (at which point something else may fail) or
upgrade GSL to >= 2.5.
