You don't. That's not an error you should get, so there's a problem with the port.
also, the error message is misleading, "/usr/lib/crt1.o". You don't compile the libc magic bits.
I'm guessing from the context you're not aware of what PIC is.
Yes . . .by the way, I did notice that the error diagnostics referred to
*.o objects, specifically,
"collect2: error: ld returned 1 exit status". Actually I am reasonably knowledgeble of the process having
blundered 
into the esoteric world of Unix and C programming back in the late 1980's. BTW, this is an excellent read (for interested readers) of the
compile process:
https://courses.cs.washington.edu/courses/cse378/97au/help/compilation.html . . .and I'll add that I tend to refer to the whole process of preprocess, compile, assemble, and link, collectively as "
compiling". (I actually started my programmer career in an IBM OS360 shop, punching COBOL code onto hollerith cards using an 029 card punch machine, and finally dumping them into a card reader to
compile the program.)
Also, I would appreciate clarification of what PIC is or implies
That's a linker error on a dependent port (trousers). I'd try a 'clean' then fresh rebuild of apache24 and all it's dependents, assuming you've not already done so. I've seen this before and although I don't remember the circumstances, I'd hazard a guess that something made trousers build in an unusual way.
Yes, following a successful isolated
portmaster /usr/ports/security/trousers, I did re-do Apache24 and it did install as advertised.
Sorry I'm not familiar enough with portmaster to suggest the right set of flags.
What I have discovered by experimenting with
portmaster trousers is that
included in
/etc/make.conf will override portmaster from default use of Clang and use the GCC. To my chagrin, using the GCC results in the error; Trousers
compiles and links successfully when using Clang. I have repeated and reproduced this process.
I suggest opening a PR against the port in question.
Do you think this should be reported . . .regarding the use of GCC?
Finally, I want to thank both of you gentlemen for your suggestion and help.
