Xgboost: g++: Fehler: libgomp.spec: Keine solche Datei oder Verzeichnis

Hallo Leute,

Ich versuche, xgboost auf meinem Windows 7-64-Bit-Computer zu installieren. Dieses Problem trat immer wieder auf. Nicht sicher, was ich tun soll.
Ich habe genau so vorgegangen wie im Thread http://xgboost.readthedocs.org/en/latest/build.html. Und auch die mingw32-make.exe in make umbenannt. exe. Ich verwende den TDM-GCC-Compiler. Die vollständige Fehlermeldung lautet:

Danke, jede Hilfe geschätzt.
