Thanks Ken. Actually, I made some progress on the causes of the hang and observed that GCC optimization flag -O2 is causing the problem.
When I manually remove -O2 and replace it with -O1 (line 6559 & line 7380 in configure script in unix folder) then the compilation seems to proceed properly. However, I know this is a bad solution, since the make gets stuck down the line for package itcl4.1.1 for the same reason. The optimize flag is -O2 in that configure script. I wonder, why the -O2 should have problem in my configuration. BTW, the VM has enough resources - 6G RAM & 128 GB HDD (LFS partition).
