樽家です。
tcl.hが無いのにコンパイルをしようとして失敗します。
mkmf.logを見ると次のようになっていました。

"cl -nologo -E -I../../.ext/include/i386-mswin32_90 -I../../../include -I../../../ext/tk    -DPACKAGE_NAME=\"\" -DPACKAGE_TARNAME=\"\" -DPACKAGE_VERSION=\"\" -DPACKAGE_STRING=\"\" -DPACKAGE_BUGREPORT=\"\" -DHAVE_NO_LPFN_DECLS=1 -DHAVE_NO_FINDEX_ENUMS=1 -DTCL_CFGVAL_ENCODING=\"cp1252\" -DTCL_CFG_OPTIMIZED=1 -DTCL_CFG_DEBUG=1  -DHAVE_UXTHEME_H=1 -MD -Zi -W2 -wd4996 -O2sy-  -Zm600 -I/mingw/include conftest.c -P"
conftest.c

checked program was:
