LinuxQuestions.org - Error installing Alsa (Error copying pcm

Hi

I'm a newbie and have just installed Mandrake 9.2 on my IBM thinkpad i1400 series.
The sound card is a Yahama OPL3SA chip, it is not detected during the installation so I decided to download and install the ALSA driver.
After locating the linux kernel correctly I exectuted the .configure command for my settings. ( ./configure --with-cards=opl3sa2 --with-kernel=/usr --with-sequencer=yes;make;make install)

And everythings runs smoothly untill it tries to copy the pcm_lib.c file.
I get error 127 during the copying.
If somebody could help me and/or see any other errors in the text below I would deeply appericiate it.
