Resolving dependencies...
Error: cabal: Could not resolve dependencies:
[__0] trying: internetmarke-0.0.4 (user goal)
[__1] trying: base-4.16.3.0/installed-4.16.3.0 (dependency of internetmarke
+/-splitbase)
[__2] next goal: HPDF (dependency of internetmarke)
[__2] rejecting: HPDF-1.6.0 (conflict: internetmarke => HPDF>=1.4 && <1.5)
[__2] skipping: HPDF-1.5.3, HPDF-1.5.1, HPDF-1.5.0 (has the same
characteristics that caused the previous version to fail: excluded by
constraint '>=1.4 && <1.5' from 'internetmarke')
[__2] rejecting: HPDF-1.4.10 (conflict: base==4.16.3.0/installed-4.16.3.0,
HPDF => base>=4.5 && <4.12)

HPDF-1.1, HPDF-1.0, HPDF-0.3 (has the same characteristics that caused the
previous version to fail: excludes 'base' version 4.16.3.0)
[__2] rejecting: HPDF-1.5.2 (conflict: internetmarke => HPDF>=1.4 && <1.5)
[__2] fail (backjumping, conflict set: HPDF, base, internetmarke)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: base, HPDF, internetmarke
